Over-the-knee Rider boots faux leather and spandex

I tried to look for the designer inside but I can't see that far down he to them but they are full of it with the thick spandex material on the back. Only worn twice they are very tight on my foot I need a wide shoe I wear a 8 and a half and they are at eight and a half but they fit like a size 8 Very good condition and very stylish.
