FWIW, I own two pairs of Malavitas in a large. One is the Restricted and the other the regular. The Restricted I just bought on Saturday from a guy who wears a size 11 and the larges were too big for him so he went with the medium. I also wear the Ambush but in a size 13. There's still a couple holes left on the straps on mine (I tend to strap as tight as can be as well tho) to move.
