The size guide and return policy is right on the website.
It’s not rocket surgery.
As usual you don't know what you're talking about,, FACT> I bought Gaitors [Large] that supposedly fit up to size 12 per the 'size guide' . I wear size 11 regular width, the Large size Katana Storm Gaiter adjusted all the out wouldn't fit over Nike gym shoes. They barely fit me while wearing only sox .
The XL fits well, they obviously don't make gaiters for someone who wears 13-14 size.
