I'm 5ft 10" and average 150lbs but I walk like I have lead weights strapped to my ankles. I hit my heel hard and have trouble finding shoes that don't weigh a ton with adequate cushioning. In that sense, these ASICS are truly amazing! Lightweight, padded. Seriously, the first day I put them on I shaved for over a minute and a half after my 5 mile run. ! I ran into a small problem and it goes like this: Some of the reviews I read said that these shoes felt unstable at times. Until now I never knew what the term meant. The heel wobbles a bit, almost like it's a little too high or something. Strange, it's only really noticeable when walking and not when running. Considering it has nothing to do with my running I won't complain too much as this is probably one of the best pairs of shoes I've bought in the last 10 years.
