Offers great support for HIIT and strength training workouts.  I'm not a runner so I can't attest to how they would do as a running shoe but I do wear them on 30-45 minute walks with the dog and they are comfortable. I am a size 7 in a dress and casual shoe but as I always do with tennis shoes I sized up one size to an 8 and they fit perfect.  Be aware, like most Nikes they do run a bit narrow.
