I'm a regular runner, not athletic or semi-athletic, so these shoes were completely different and new to me. I really like the zero fall aspect as it seems to improve my form and SIGNIFICANTLY reduces knee pain. The pillow is good too, which ultimately means I can walk more days a week without pain. I wasn't expecting this, but Zero Drops definitely work better on my calves, which by definition is pretty obvious. These Nike sneakers got used to it in a few minutes because they are much wider…
