This set of Arch supports come in a 2 pair pack. 1 off white and 1 black. They are to help with the sore feet at the end of the day. I am using these in different shoes right now to get a sence if they will work for me. I have very flat feet. No arch at all. So far these seem to be working. I wear a couple hours at a time. Im doing this to biuld up the feel of having something under my "arch". I would try this if you to have no arch.
