Women are advised to size down one full size (ie: a women's USA size 8 would take a men's boot size 7). *STUD/CLEAT COMPATIBILITY: boots with rubber outsoles will take Hardbite Wading Studs - RUBBER; boots with the felt sole will accommodate Hardbite Wading Studs. No other stud/cleat is recommended for either boot style.
