I been a selective Amazon shopper for years. I never had to return a product until know. This product was manufactured by guess who? Of course they have no idea about standard American sizes. I read what others said about the product and decided to place my order with thier suggestions. I am a big man so my standard size is size 14, so ordered a size 15. When placing the order and receiving it, to my surprise the item did not fit. You mean I need a size 16??? and did I mention that with my medium width foot the item was to narrow. ...very uncomfortable. No, I would not buy this product or suggest anyone to buy the product...HELL NO!
