I usually wear size 10, after reading the reviews I decided to order 9.5, which unfortunately turned out to be a mistake. I sent them back and immediately ordered 9.9 and 8.5, we are both too big. I finally settled on a size 8 pair. I think it's worth it as the size 8 blue suede was only $20. Designer swim fins. Sure, these are great shoes, but if either of you pay the $80+ price I'm seeing for some colors, you're in for a big surprise. At $20, they definitely live up to the bill for a good dog walking shoe. : Update: December 26, 2020 I have worn them less than 10 times. Every time I do this they hurt my legs. They're not even good enough for lawn mowing shoes or garden shoes. Honestly, they're just gathering dust on my shoe rack because they're so bad.
