The man was very professional & knowledgeable. I bought for myself & a friend. And when I got home I bought 3 more pair! I will be telling my friends about this product.i even put these in my Ecco shoes which are pretty comfy to begin with. Might I suggest more advertising, I almost walked on by as I thought these were the good feet arch support which in my view are an expensive scam. They do nothing for my problem which is the loss of fat on the soles of my feet. Needless to say I am quite happy with my purchase!
