Are leg warmers with grip patterns just a desperate attempt by manufacturers to make money off of clueless cyclists, or do they actually serve some sort of purpose beyond making your legs look like theyre wearing fuzzy knee-high socks? Do the tiny little grip bumps on these things magically generate more power or improve aerodynamics, or are they just there to give you a slightly better grip on your bike seat when you inevitably crash due to your own incompetence? If the science is so convincing, then why dont pros wear them in the Tour de France, and if its just for amateur hour, then why are they so freaking expensive?
