Not for guys with really big feet, however (11 is the largest size available right now). Limited quantities. They're pretty comfortable, and will take minutes, if not hours, off your lap times ....... Or maybe not .............. Autocrossers wearing these may get to the finish before they leave the starting line, and of course, they're known to ward off cones.
