I am a new cyclist. I have about 400 miles on my bike and I am currently training for a century ride in November. As my mileage has increased I have developed some serious toe pain. Both feet start going numb from the pinkie toe in to the big toe around the 20 mile mark by the 35ish mile mark (depending on the amount of climbing) my toes have gone from numb to a severe burning/lack of circulation feeling. It is painful enough that I have to stop every couple of miles. The pain subsides almost instantly upon standing.

I have had a professional fitting. I currently have shimano SPD pedals and Northwave shoes with blue superfeet insoles. The shoes have a very wide toe box and I have a narrow toes.

Help! I am trying to get a dr appt - but I would love to hear some theories. I am at a loss, as well as my coach and the guy who does my fitting.
