I ran up to 11 miles at one time on trails with the On Cloudultra and I experienced no foot pain or discomfort. However, once you start running fully into your workout, your feet seem to stay in place. Actually, your foot can move around a little and slide. The On Cloudultra kind of have a flat bottom with no real arch.

The toebox is open and wide enough to give the toes some room to wiggle. The shoe is not too narrow, nor too wide. I ordered a half-size higher than normal, and that was a great choice. In a picture of the shoe, you can see the holes of air in the bottom cushion. It is like you are walking on clouds, which is perfect for long distances. The On Cloudultra gives a feeling like running on a Hoka shoe. I tried running a sprint on a flat dirt path, and the shoe seems to absorb every step and slow me down. It can be bothersome when you just want to go out for a fast, short run. With the cushioning, the shoe is a little bouncy. If that’s the case, look at the collection of competitive trail running shoes. Do not buy this if you are looking for a fast shoe.

Buy this shoe if you are looking for a grippy ultra-marathon trail shoe that is versatile enough for some road running without discomfort.Your browser does not support the video tag.
