This was the lowest priced toe stretcher that I have found. The product works well and I noticed a difference in my crooked toes and hammer toe. However, I thought I would need a large one since I take a size 12 shoe, but it is too large and a bit uncomfortable. I think a medium or even a small would have worked better. It would be nice if they had suggested sizes based on shoe size. In spite of the mis-comfort, my hammer toes did temporarily straighten out with the first use and I will continue to use it.
