I'll admit to being a bit of a Gear Junkie and the desire to buy "nice outdoor things." Icebreaker, Arc'Teryx & more are some of my favorites...well now adding ON to that list. The fit and reactivity on these is phenomenal, and while I do run outdoors in them, due to the lower profile of these shoes I most often use them for cross-training classes. Perfect for treadmill work, HIIT training, weights & more. Highly recommend!

As a seasoned marathoner (2:55 PR last year), I'm not in the habit of switching to new shoes brands. A friend of mine recommend ON running, so ever the skeptic, I googled reviews which were favorable enough to merit a try. These are the real deal. I've been running in them for about 3 weeks. They are incredibly light weight, comfortable but not overly cushy, supportive but not annoying structured. I had a been running in NB Fresh Foams for last several years, and these are so much a better shoe. Also, I have decently wide feet, so I can't play in Adidas' narrow runners. The Cloudflows fit perfectly but not too snugly. The toebox has room to breathe and the upper does not dig. I've done longer and shorter runs, concrete sidewalks to packed dirt, and these ONs are a sweet ride. I am a convert!
