This shoe is terrific for walking. I have a problem with soreness in the knees and walking had become difficult, if not painful. I purchased the shoe based on a recommendation by my doctor. They are a god-send!. The sole reduces the impact to the point where walking is no longer painful and I was able to get back into my walking 3 miles every morning before work. Without these shoes I don't think it was possible. The sizes seem to be spot-on, at least for my foot. If there is a downside, the shoe does require you to adapt a different style of walking, but this is neither difficult or painful. I would recommend these shoes without hesitation.
