WOW listening to all you people here is something. I have a total knee which I later broke the femur bone on that leg so now it houses a pin to my hip as well. The other knee is starting to give me trouble. Besides that I have a pinched nerve in my lower back. I have to go barefooted around the house in which I to have concrete floors with tile and standing on those gel mats are not for me at all I guess it really does depend on the individual after all. Even shoes with arches are bad for me I have to take them out or not buy. I did love the crocs but since my back problem I had to give them up. You guys are wonderful here and I am addicted to the board
Good luck to you what ever you choose to do
