Ballet heels are usually the fetishy icing on the cake at exotic footwear stores, and they’re typically designed as boots, to allow for the lacing that “locks” the wearer into the inability to walk, or at least not very easily. (and yes, some come with literal locks if metaphors aren’t good enough.) Punitive Shoes, a site that specializes in extreme heels, goes beyond boots to offer ballet mules, ballet maryjanes, ballet slingbacks, ballet ankle straps, even what looks sort of like ballet saddle shoes — not only offering an S&M fashion staple elegantly redone in classic feminine styles, but also giving the wearer a restraint that literally slips off the feet.
