All four of these shoes are built with a relatively low heel: a key for fast, efficient race walking technique. Running shoes generally possess higher, more shock-absorbing heels because of the excessive stress caused by running mechanics. While the NB 110s, Asics Tiger Paws, and Hersey’s all have an effectively low heel, the NB 713s are comparatively higher. Still, the NB 713s have the lowest heels I have recently seen on training shoes designed for running, and should be seriously considered by race walkers looking for stability, cushioning and longer life. In contrast, the heels of the NB 823 (the more typical running shoe) are roughly twice as high as the NB 110s.
