i seem to have conquered the hands problem awhile back (yep - gloves, stem height, seat angle, varied bar postions, all that), but on particularly long rides (30+ miles) my toes start going numb. i run clips and straps, so the obvious answer would be to loosen 'em, but i've tried it and the lil' toes still get all tingly a few hours in. what else could it be? maybe i finally ought to convert to clipless?
