Jump rope, Sprint, Squat, Box Jumps, are some of the exercises I typically do in fitness shoes. These held up well, and allowed for terrific support, while promoting forefoot strike while running (my calves were a little sore the following day as proof). The only are lacking is on the forefoot. Lateral support in the toe box area is adequate, after about five workouts, the forefoot area started to stretch laterally. I did not experience this with any of my alternative Inov-8 shoes(Which held their shape after dozens of workouts and continue to do so). I wore them all day for a 12.5 hour shift on my feet, and they were perfectly comfortable.
