I ran 40 miles with the Cloudsurfer 2 vs. On Cloudmonster 2 — which shoe should you buy?
The On Cloudsurfer 2 is a comfortable daily trainer with a smooth, rockered ride. It's softer than the Cloudmonster 2, as well as being lighter and cheaper, but it's not the most durable shoe and also feels a bit flat on longer runs or when running at faster paces.
The On Cloudsurfer 2 and On Cloudmonster 2 are both comfortable running shoes that are great for daily training, but they have different feels on the run that may make them suitable for different kinds of runners.
I've done around 40 miles of running in each shoe, and below you'll find my direct comparison of their relative strengths and weaknesses. Check out our On Cloudmonster 2 review and On Cloudsurfer 2 review for a more detailed take on each shoe.
The On Cloudmonster 2 is the more expensive of the two shoes, costing $180 / £170 compared to $160 / £150 for the On Cloudsurfer 2. However, the Cloudmonster 2 is also the older of the two shoes, so it's a little more likely to feature in sales — it's currently in the On last season sale for $140, so it's worth checking when comparing the two shoes.
The On Cloudmonster 2 is currently available in 11 colors, while the Cloudsurfer 2 is currently available in five colors.
At 10.7oz for a US men's size 9.5, the Cloudmonster 2 is the heavier shoe, with the Cloudsurfer 2 tipping the scales at 9.7oz in the same size.
Part of that weight difference is down to the fact that the Cloudmonster 2 has a higher stack of foam in its midsole and a lower drop with a 6mm heel-to-toe offset — the Cloudsurfer 2 has a 9mm drop.
I found that both shoes fit me well enough in my normal running shoe size, but as someone with a narrow foot, the Cloudmonster 2 did feel very wide and roomy in the toe-box — I preferred the snugger fit of the Cloudsurfer 2.
The Cloudsurfer 2's upper is thicker and more padded around the tongue and collar, with the Cloudmonster 2 using a more breathable material and a thinner tongue.
Both uppers flex well and support the foot securely around the midfoot and heel, but the Cloudmonster 2's upper might feel less oppressive if you're always running in hot conditions.
By far the biggest difference in the design of the two shoes is how their midsoles are set up. The Cloudsurfer 2 uses On's soft Helion foam with a series of holes designed to collapse like dominoes and create a rockered feel to the ride.
This CloudTecPhase design makes the ride smoother than that of the Cloudmonster 2, which has three layers of foam in its midsole.
The Cloudmonster 2 uses Helion foam for its top layer, and then the bottom is On's distinctive CloudTec pods, which are made from a firmer and heavier material than Helion.
There is also a nylon-blended plate, "Speedboard," in the midsole of the Cloudmonster 2, which helps stabilize the high stack of foam and speed up the transition from heel to toe.
Both shoes have pods on the outsole of the shoe, with rubber covering the forefoot and heel, leaving some exposed foam in the midsole.
I didn't notice a difference in the grip of the two shoes, which have both delivered reliable traction in the wet, and neither outsole is showing any undue signs of wear and tear after around 40 miles of running.
I used both the On Cloudsurfer 2 and On Cloudmonster 2 for a variety of training runs, mostly at an easy pace, with some faster intervals thrown in.
In my testing, I found that both shoes excelled in similar runs and had the same weaknesses — both are good for easy runs and neither feels that responsive at pace, but they have quite different ride feels.
The On Cloudsurfer 2 is a lot softer than the Cloudmonster 2, and the rocker is very noticeable on the run. It has a smooth feel that feels great for ticking over at a relaxed pace.
At faster paces, I found that the soft foam flattened out and the shoe didn't give a lot back in terms of energy return. It's quite a light shoe and you can run quickly in it, but it doesn't feel as good as it does for easy runs.
In contrast, the Cloudmonster 2 has a firmer ride and doesn't roll through as smoothly, but the midsole setup is a bit more responsive and bouncy.
I found the Cloudmonster 2 better for long runs than the Cloudsurfer 2, and although it's heavier, it was as good for faster runs as the Cloudsurfer 2 because the midsole foam provides more energy return.
Overall, neither are shoes I'd describe as exceptionally versatile, but both are good daily trainers that work well for easy runs and can handle speedwork reasonably well.
I'd pair either with a lighter shoe for fast runs myself, but if you want one shoe for everything, both can do the job.
My preferences skew towards lighter and rockered running shoes, so I'd reach for the On Cloudsurfer 2 myself. I found it more fun to run in, and it was easy to get into a good rhythm on easy runs thanks to the rockered midsole.
It's also cheaper and lighter, and the fit is a little better for me because I have a narrow foot. I love the look of the Cloudsurfer 2 as a casual shoe, too.
The On Cloudmonster 2 has its strengths, though. I think it will be more durable thanks to its firmer midsole foam, and it holds up better on long runs when the Cloudsurfer 2 can start to feel a little flat. It also feels more natural when walking than the softer Cloudsurfer 2.

The best new launches (so far) in July: Hoka, Dyson, Biodance, Saie and more
This story is part of NBC Select's New & Notable column, where we highlight our favorite product launches. We will continuously update this article throughout the month with new releases we think you should know about. Footwear and apparel launches According to our testing, the Hoka Arahi is one of the best walking shoes, and the brand's new model keeps feet centered and cushions them better than the previous model. It's made with softer foam, has an improved stabilizing system to prevent overpronation and is designed with a mesh upper that has reflective details. The Arahi 8 earned the American Podiatric Medical Association's Seal of Acceptance, and it's available in regular, wide and extra-wide sizes for men and women. On iterated on the Cloudeclipse, one of NBC Select reporter Zoe Malin 's favorite running shoes, to design the new Cloudsurfer Max. Made for long-distance runs, the shoe has two layers of On's CloudTech Phase cushioning system and Helion foam, making for soft landings and smooth transitions. The sneaker comes in men's and women's sizes. Malin has been running in the Cloudsurfer Max sneakers for about two weeks and logs six to 12 miles in them per wear (the brand sent her a courtesy sample). 'The cushioning on these takes so much pressure off my knees, preventing them from feeling achy, especially once I get to mile 10 or so,' she says. 'They have a lot of foam and a higher stack height, but they don't look intimidating at all, which makes me gravitate toward them when I want to wear a max cushioned shoe.' Brooks' Hyperion series shoes are speedy and lightweight, and the Hyperion Max model adds a thick layer of foam cushioning to that formula (at the cost of being a little heavier). The latest Max 3 has significantly more cushion than the Max 2s, leading to a much taller 46 millimeter stack height (up from 36). Like previous models, it has a nylon plate built-in to help propel you forward with each step. The shoes are available in men's and women's sizes. The Hyperion Elite 5 is the most race-focused of Brooks' Hyperion lineup — it's the lightest by far, and has a stiff carbon plate for maximum energy return in each step. The Elite 5 is lighter than the previous version, with a minimal upper and new cutouts in the midsole. Saucony released a new version of the Hurricanes, but they're still the brand's most cushioned shoes for daily runs. The 25s have a thick layer of two types of foam, giving them a soft, bouncy and responsive feel, and a different shape compared to the 24s to better compliment the shoes' wide, broad, stabilizing platform and high sidewalls. The sneakers, available in men's and women's sizes, are also made with a soft sockliner and flexible, durable rubber outsole. Allbirds redesigned its Tree Runner sneaker to make them more comfortable so you can wear them for hours while traveling, commuting or running errands. The shoes now have dual-density cushioned memory foam insoles and a more contoured shape underfoot to support your stride, plus midsoles made from the brand's SweetFoam material, which is derived from sugarcane. The wool-blend that lines the sneakers' collar and tongue give them a snug, plush feel, too. You can clean these sneakers, available in men's and women's sizes, in the washing machine. This full-coverage T-shirt bra is seamless and won't show under most clothes, according to the brand. The bra is made with airy, breathable microfiber fabric, and it has underwire cups with a keyhole detail in the center. The wide cushioned straps are adjustable and convertible, so you can wear them straight or criss-cross. The bra comes in band sizes 30 to 42 and cup sizes B to G. Tech launches Samsung unveiled new mobile hardware this month including the next iteration of its flagship smartwatches. Samsung's Fold series phones fold in half like a book, and this latest version has larger screens while being significantly thinner and lighter than the Z Fold 6. When folded, the phone is 8.9 millimeters thick, that's only a bit more than a regular phone (the iPhone 15 Pro, for example, is 8.25 millimeters thick). The Z Fold 7 also has a new 200MP main camera, up from 50MP in the Z Fold 6. Samsung's Flip series phones, on the other hand, fold in half vertically, like a clamshell or steno book. This updated version improved the exterior screen — it's bigger and faster than before, making the phone easier to use when folded closed. The Nintendo Switch 2 launched last month, and with it were not many new games for the system. Donkey Kong Bananza is a brand new game for the Switch 2, and, like Mario Kart World, may be reason enough to buy a Switch 2 (if you've been waiting). In it, you play as Donkey Kong and explore a large underground world, largely by smashing your way through with your fists. The brand sent Rabinowitz a copy at launch, and he's been hooked. 'I've only played it for about four hours, but it's been imaginative, charming and delightful for each and every minute,' he says. Meta's newest smart glasses and collaboration is the Oakley Meta HSTN. Like the Meta Ray Ban before them, these look mostly like normal Oakley sunglasses on the outside, but have cameras and microphones built-in that let you listen to music, take calls, take pictures, capture video and talk to a voice assistant. The Oakley Meta HSTN also has higher quality cameras and longer battery life compared to the Meta Ray-Ban, according to the brand. This is a minimal wireless charger from one of our favorite travel tech brands. It's a wireless charging puck that sticks straight into any wall outlet. It supports MagSage charging and the latest Qi2 technology, so you can be sure it will charge all your wireless devices as fast as possible. The magnets will keep things like your iPhone upright so you can see and use them as they charge. Amazfit is known for making affordable wearables, and the Balance series is one of their premium all-in-one smartwatches. This model has a compact 1.5-inch scratch-resistant sapphire glass screen (an Apple Watch Series 10 screen is either 1.6 or 1.8-inches by comparison). It also has dual-band GPS and downloadable maps, so you can navigate even without a signal (a rare feature at this price). The Balance 2 gets up to 21 days of battery life, according to the brand. This is Amazfit's first screenless wearable — it's a soft wristband that looks very similar to something like a Whoop band. It tracks health, sleep and fitness basics, and displays all your data and analysis in the Zepp app. The Helio Strap gets up to 10 days of battery life, and, unlike some competitors, doesn't require a subscription fee. Nothing is known for making eye-catching products, see the Nothing Phone (3a) or Nothing Ear(a) to get the point. The Nothing Phone 3 is the brand's first 'flagship' phone, priced at $799, exactly the same as the iPhone 16 and Samsung Galaxy S25. It separates itself from those phones with a distinct design on the back, with asymmetrical glass, patterns, and camera placement. Also on the rear is a tiny LED display that can show you if you have unread notifications and display things like the time, timers, a compass and more. This is the first pair of over-ear headphones from the brand, and, true to form, they have a tech-y, transparent look to them. They have noise canceling and transparency modes, on-ear controls and high-quality playback when using wired USB-C cable. The headphones get up to 35 hours of battery life with noise cancelling and up to 80 hours without it. Marshall makes some of our favorite portable Bluetooth speakers — they're typically stylish and sound excellent. The Middleton II sits between the three pound Stockwell II and 6.2 pound Kilburn III in terms of weight, size and price — it's easy enough to carry in a bag or in your hand, but gets louder and lasts longer than smaller models. It's IP67 dust and waterproof and gets over 30 hours of battery life, so you can bring it on any beach trip or vacation without worry. Beauty and wellness launches You can use this paste as a spot treatment, cleanser or clarifying mask to reduce active acne and prevent future breakouts. It's made with 2% salicylic acid to target pimples, charcoal to absorb excess oil and cica cenella to prevent dryness and restore the skin barrier, according to the brand. It's safe for all skin types, according to Kiehl's, and you can use it daily. Biodance 's latest hydrogel mask essentially lets you do a salmon sperm facial at home. It's soaked with a serum made with PDRN, an ingredient derived from salmon DNA, and salmon egg extract to support skin recovery and renewal, according to the brand. The serum absorbs into your skin in about three to four hours, causing the mask to become transparent. You can also wear it overnight. Saie's baked setting powder disappears once you brush it on top of makeup, preserving your look for about eight hours and leaving behind smooth, bright, blurred skin, according to the brand. The powder comes in five creamy, translucent shades, absorbs excess oil and is made from clean, hydrating, noncomedogenic ingredients like hyaluronic acid and squalane, plus clay minerals like hertorite, mica, silica. Peach and Lily added two new acne-safe skin care products to its lineup this month: the Snail Rescue Ultimate Eye Gel and the Super Fade Discoloration Moisturizer. The eye gel is made with 70% snail mucin, 2% niacinamide, birch juice and cica to hydrate, brighten and smooth fine lines, according to the brand. You can use it daily, and it has a cooling effect, so it depuffs, too. The moisturizer helps hydrate skin, even out your complexion and fade dark spots. It's formulated with ingredients like 5% stabilized AHA, 4% niacinamide, glycerin, panthenol and squalane, which Peach Slices says leaves skin smoother and brighter. Calm irritated skin posthair removal and help treat razor burn and ingrown hairs with this jelly, which is made with 0.02% hypochlorous acid, an antibacterial ingredient. It earned the National Eczema Association seal, so it's safe for sensitive skin, and has a cooling gel feel. You can use the Repair Jelly directly after hair removal, daily on irritated patches or as needed during flare ups. This primer is a skin care-makeup hybrid — it blurs pores and hydrates skin to make a smooth surface for makeup, and addresses hyperpigmentation through ingredients like niacinamide, tranexamic acid and amla extract. It's made for those with melanin-rich skin, but anyone can use it. It has a gel-cream texture that leaves behind a dewy finish, according to Kulfi. Although anyone can use it, Laura Geller made this gentle makeup removing cleanser for those with mature skin. It melts away makeup, including waterproof products, and removes dirt and grime without stripping the skin and leaving it dry or tight. The cleanser has moisturizing ingredients in its formula like shea butter, olive oil and plant-based peptides, making skin feel soft and supple after use. Hair care launches The Airwrap Co-anda2x is Dyson's most powerful multistyler and hair dyer yet, according to the brand. It has a newly developed motor that Dyson says offers double the amount of air pressure and 30% more power compared to the original Airwrap, helping dry your hair faster, improve curl pattern and create sleeker styles. The tool has smart heat sensors to prevent hair damage, and it's also smaller and lighter than the original Airwrap. It comes with six attachments, including a finishing attachment and an upgraded round brush. When you add an attachment, the Airwrap automatically recognizes it, adjusting its heat and airflow settings accordingly. The Airwrap also connects to the MyDyson app to identify your hair type and create a personalized curl pattern based on your styling preferences. IGK added two products to its Good Behavior line this month, a serum and a hairspray, both of which block out humidity, make hair look smooth and sleek, and mitigate frizz, according to the brand. The Supreme Seal Serum, which you apply to dry, styled hair, tames flyaways and also provides UV protection. The Flexible Anti-Frizz Hairspray doubles as a heat protectant up to 450 degrees Fahrenheit, has a medium hold and doesn't make strands feel crunchy after use. NBC Select commerce editor Lindsay Schneider has been testing the Supreme Seal Serum (the brand sent her a courtesy sample). 'I like to run this through my dry, frizzy ends for instant taming,' she says. 'I apply it like I would a hair oil and notice similar results. It's been a real life saver during the humid temps in New York.' Moroccanoil's Texture & Volume Powder gives hair body and helps lift its roots. It's buildable, so the more you apply, the more volume and texture it adds to hair. The powder is made with argan oil and a mineral compound to nourish strands and prevent them from lying flat, creating a fuller look, according to the brand. It has a semi-matte finish and Moroccanoil's signature scent, making it deodorizing. The powder is made for those with fine to medium hair, although anyone can use it. This hair mask helps reverse the signs of dry, brittle and damaged hair. It's made with hydrolyzed moringa protein, which bonds with keratin sites to strengthen their structure and restore elasticity, as well as vitamin C and tamanu oil to minimize breakage, seal split ends and make hair soft and shiny, according to the brand. Innersense recommends using the mask in place of conditioner every two to four washes, or when you see signs of damage. Home and kitchen launches This is Tineco's most advanced floor washer yet, according to the brand. The self-cleaning system automatically adjusts its suction power and water flow as it detects messes. It also has a stream function to dissolve stains and is made with an anti-tangle brush head that won't get clogged with hair and pet fur. The floor cleaner's LED headlight illuminates dirt so you know exactly what to clean, and its 3D light changes color based on its cleaning status. The floor appliance also lays flat, letting you reach under furniture, alongside baseboards and into corners. Windmill makes one of our favorite air conditioners, and the brand just launched its smallest, most compact version yet. The AC Lite Series is a 5,000 BTU model that can cool spaces up to 150 square feet, like bedrooms and offices. Similar to the brand's other cooling appliances, this AC connects to the Windmill app, letting you control it from anywhere, and it responds to voice commands. You get a remote and installation kit with your purchase. The Laundress specifically formulated this laundry detergent and fabric spray to clean sweaty fabric and get odors out of workout clothes. The Activewear Detergent is best for fabrics like nylon, spandex, cotton and synthetics, according to the brand. It has an enzyme blend that targets odor, sweat stains and buildup while maintaining fabric's integrity so it doesn't fade or stretch out. The Activewear Fabric Spray, on the other hand, is made to freshen up activewear, gym bags and shoes between wears. Both products come in the brand's new Marine scent, which has notes of bergamot, mandarin, amber and ocean plants. Brezza, the new sister brand to babyBrezza, launched its first product: The Supermix. It's a countertop appliance that dispenses water and nutritional powders like protein powder, measuring everything precisely so you don't have to. The Supermix holds up to one pound of powder and up to three liters of water — you can make up to 12 shakes before needing to refill anything, according to the brand. Using the buttons on the appliance's screen, you can adjust its settings to specify how much powder and water you want to dispense at a time. The Supermix comes with an electric, rechargeable mixing cup, but you can put any cup up to 24 ounces under the spout. Why trust NBC Select? To round up the best new launches each month, reporters Zoe Malin and Harry Rabinowitz choose products they think NBC Select readers should know about. They include products from brands NBC Select has previously covered, or brands staffers recommend. Malin and Rabinowitz also regularly try new product launches to share their first-hand experiences.

'Earthquake inside Apple' — AI efforts just dealt another major blow
When you buy through links on our articles, Future and its syndication partners may earn a commission. Apple's push to catch up in the AI race has hit another serious roadblock. The company has lost Ruoming Pang, the highly respected leader of its foundation models team, to Meta — and insiders say the ripple effects are already being felt across Apple's AI division. Pang, who joined Apple in 2021 from Google DeepMind, was central to the company's efforts to build its own large language models (LLMs). His departure, along with that of several close collaborators, signals deeper unrest within Apple's AI ranks. As reported by The Information, Pang's exit and its aftermath has led to an 'earthquake inside Apple." Why Pang's exit matters Pang was known for his hands-on technical contributions, including developing a key open-source training tool for Apple's AI models. Under his leadership, Apple made strides in shrinking LLMs to run efficiently on iPhones, a critical part of its 'on-device AI' strategy. But those advances came with internal tensions. According to reporting from The Information, Pang's team had wanted to release some of Apple's AI models as open source earlier this year. This move could have shown progress while inviting collaboration from outside researchers. But Apple exec Craig Federighi reportedly shut it down, concerned it would expose performance compromises Apple made to run the models on iPhones. That disagreement was just one of many signs of friction between Apple's research-driven foundation models team and its product-focused leadership. A shift in power (and priorities) Earlier this year, Apple reorganized its AI efforts following delays to its revamped Siri assistant. The Siri team was pulled from longtime AI chief John Giannandrea and placed under Federighi, who also oversees Apple's software division. Meanwhile, Pang's team remained with Giannandrea, but the separation highlighted a growing divide between R&D and product execution. Now, with Pang gone and several of his top researchers either leaving or exploring offers from OpenAI, Anthropic, and Meta, Apple faces a major talent drain at a critical moment. Bloomberg recently reported that Apple is testing outside models, including those from OpenAI and Google, to power Siri, a move that reportedly disheartened many on the internal AI team. The bigger picture While Apple made headlines with its Apple Intelligence announcement in June, integrating ChatGPT into iPhones and showcasing writing and image-generation tools, the company's own foundation models remain behind closed doors. Insiders say there's still a lack of clear direction about whether Apple wants to compete head-to-head with models like GPT-4 or build more narrow, hardware-optimized tools. In an interview with Tom's Guide following WWDC 2025, Craig Federighi, Apple's senior vice president of software engineering, and Greg Joswiak, the senior vice president of worldwide marketing, made it clear that Apple doesn't want to make a chatbot. Without Pang's leadership and vision, some fear Apple's internal AI efforts could stagnate, or become overly reliant on outside partners. Others remain optimistic that the hiring of Zhifeng Chen, a former Google engineer now leading the foundation models team, will bring fresh momentum. Either way, Apple's AI ambitions face a decisive inflection point. As rivals like Meta, OpenAI and Google continue to poach top researchers and ship headline-grabbing models, Apple must prove it's still a serious contender in the generative AI era. More from Tom's Guide Claude 4 vs ChatGPT explained: What each AI does best — and how to choose the right one No, The Simpsons didn't predict that — here's how AI is fueling viral hoaxes (and how to spot them) I upgraded to Alexa+ for my busy family — here's what it did surprisingly well Sign in to access your portfolio
