Moxi Skates Thunder Thigh Shorty Shorts Size C or Extra Small. Brand new, never worn. Unfortunately too small for me. These shorts are made for the roller skater, designed by the roller skater. It's no secret that roller skates are powered by the thighs and buns and require clothing that is comfortable, stretchy and mobile. That's why we exposed the thigh, brought them high up around the waist, and down lower in the back.
