Awesome shoe with unbelievable comfort in the toe box. Truly a great Tri shoe especially for running with no socks. For anyone with a narrow heal and wide forefoot--this is your shoe. I've definitely found mine.

Starting my running program for weight loss at 320 lbs was not as painful as in the past due to this excellent shoe! They do run about 1 full size smaller than expected so add a size when ordering. I really do love the cushion as well as the superior light weight and slip on technology! Excellent shoe!
