Hey guys, does anybody wear shoe inserts while working the sales floor? I'm a cart attendant and have just been cross trained in hardlines and my knees and feet are suffering quite badly from the not so soft flooring in spot. I purchased Dr. Scholl's "work" inserts, and they get rid of my knee pain pretty much entirely, but they still hurt my feet. Does anybody have any suggestions? I might try the "active" from Dr. Scholl's as it's specifically for people who do a lot of walking/running. I have Nike running shoes, but I guess the tile floors do a number on me even with the support in these shoes. I don't feel like paying $60 for "custom fit" inserts. Thanks for any help!
