UPDATE: 8-18-15 so i have used these since july 3rd and guess what... the heel on both are now worn... holes in them... what i'm saying is do not use these often if you want them to last. My useage was for fishing/wading... At first I loved them, five starts.. 1 month after using and the fall apart... well that's terrible quality. For the record I wear an 8 in regular mens shoes... I got a size 7 and they fit perfect.  Ended up taking the soles out because after two wears they became loose and floated in shoe while on feet.. other than that.. GREAT GREAT GREAT GREATTTTTTTT product.. great price, great seller! 95% absolutely love amazon! always stick with PRIME option!!!!
