After I purchased these flip flops, I wore them around the house for about two days. They were comfortable at first then irritation on my upper left foot began and in a few hours the pain became unbearable to wear them. I also purchased a pair of these exact flip flops from Shoe-buy for my wife (Amazon did not have her size) and had to return them due to the discomfort felt immediatly upon her trying them on. My advice is try them on in a store first.
