I think it costed me smth like 8 USD which is exactly what its worth. I really doubt that I will use it more than twice, as it will simply not survive any more. Just like one of the previous reviewers said its made of the cheap fabric they make the little one-time footy things they give you at shoe stores for trying on shoes. It lacks stretch and therefore it goves no support. Due to the fabrich being really thin its also likely to snag very easily.
I am not disappointed as I was not expecting a lot for this price, but I guess you should now the issues before you order it.
