HIIT, mountain climbers, squat jumps? No problem. Here's an ultra-flexible training shoe built for feel-good workouts. From burpees to box jumps, take on all moves in total comfort with the X-shaped Speedboard. Made with a pliable nylon blend for better forefoot flexibility during multi-lateral movements. The Helion superfoam midsole delivers cushioning underfoot, while extra padding in the heel means even more comfort. For lateral stability, the midfoot cage and star lacing system wrap securely around the foot. The breathable mesh upper is made with at least 90% recycled polyester. As with many of our shoes, the upper's yarn is dope dyed a process that requires 90% less water compared with standard dyeing techniques.

These shoes offer a really sleek design that in my opinion makes them great for both running and cross-training. The foam makes them feel lighter and more responsive than the Boston Marathons I wore prior to them. The traction pattern provides better grip on different surfaces, but especially on concrete. This shoe is really flexible gives me a lot support during my runs and training.

Great cushioning and comfortable. Typically wear Nikes and these fit well. Looks great.

Comfortable fit, no abnormal movement and comfortable for days spent on feet. Definitely intended as a running shoe but holding up well to all day wear as a physio in clinic. Avoided previously due to mentions of issues with wear of sole but no such issues in this interation. Very happy.
I got the ivory colored— so cute and comfortable from first wear! Like the previous version, they’re a little tight on top bc of my high arches, but will stretch a little and be fine. Love these!
They didn’t quite meet my expectations for comfort. Additionally, they rub against the back of my heel, so wearing longer socks is necessary.
Great shoe but had to return as falling apart then next pair have done the same! Wouldn't buy them again as don't last longer than a couple of months if that and that's with no running!
Super comfortable like most On’s. Fit standard so I got my normal size. I highly recommend these if you’re looking for a lightweight sneaker for running or walking.
Took a trip to NYC and the cute sneakers I brought weren’t cutting it. My feet hurt so bad, I was limping and desperate for comfort. These feel like clouds on. I’m happy I just bit the bullet and bought them. I wear them quite a bit and can’t get over how comfortable they are. Would definitely recommend.
I bought these for my weekly circuit at my local gym. It’s a high intensity program that varies weekly. Sometimes we run, even sprint, sometimes we squat, sometimes flip tires. I wore these today for a mixed workout that including a quick run and then some body weight exercises. The held up great. Good stability in squats/lateral movements, but still enough cushion for a comfy short run. I’ve been looking for a solution for 2 years. Recommend for the intended purpose of these shoes- cross training. Plus they look good.
