I just bought a new pair of clip less shoes a little over a month and I notice on my rides, no matter how long the ride is my toes start to go numb or get "pins and needles". I was told that it was from improper fit, but when Iím off the bike the shoes feel great. Its only when Iím riding. Can anyone tell me what the problem might be? I don't really want to buy new shoes if I don't have to and the shoes I have now cannot be returned. Any help will be greatly appreciated.
