I am experiencing numbness in my little toe and the one next to it when I'm riding for 15 miles or more on pavement and/or bike path (this is on a mountain bike turned into commuter/fitness bike). I will say that I've just begun using clipless shoes (I've already tried fixing the problem with lacing tightness/pattern). I'm wondering if it has something to do with saddle position or height and if having my foot attached to the bike is altering the way I ride on the saddle. I will say that I do enjoy riding with clipless pedals and shoes...maybe the best thing I've done to improve my biking.
Any advice on this topic greatly appreciated.
