Outdoor research crocodile expedition boot gators. These are side medium. I wear a 9-9.5 boot and these are a little big on me so I would they are perfect if you wear a size 11 or 12. Good condition, only downside and I didn’t realize when I bought them used or the past 2 years wearing them I’d I think they are both right legs. It never affected wear or really noticed any difference, just you can tell with the inside material being on the same side on both. They wear fine and I never had problems, I just bought a smaller size. 45$ tyd
