These are so cute and versatile! The product quality is surprisingly nice for the price, with clean edges and no visible glue marks. There was no weird chemical or unpleasant smell upon opening. The faux-leather material is soft, flexible, and doesn't pinch or rub against the back of the heel. In terms of fit, they are true to size and very comfortable for daily wear. They look identical to the product image shown on the app. Highly recommend!
