I have major mixed feelings about these shoes. The cushion part works fine: a nice, gentle step, which I'm sure would be easy on my knees, etc. The problem is I cannot wear these around the house: They are simply too loud. They sound like walking on some squishy, rubbery material. They are fine for a long walk but for around the house, I just can't see myself keeping them. If you live with a hearing impaired person, or alone and don't mind the noise, it may be another matter. I switched from Asics and Brooks, because the toe room is better.
