Dotsie, I'm sure you could walk three miles in them easily. The more I wear them, the less my legs and back hurt. I haven't had but one event of back spasm since I started wearing them. Today I have them on with sock, cause it's cold here!

If my husband has to go back to the bread route, I'm going to get him a pair. His feet and back hurt all the time when he's working.
