Numbness in the toes is caused by a pinching of the nerves as they pass through the inter space between the metatarsal joints. This can be caused by a collapsing of the transverse arch as load is put on the forefoot during the pedal stroke and can be exacerbated by shoes that are too narrow. The best solutions are orthotics with metatarsal pads and/or Bont cycling shoes which have a wider oblique toe box.
