I've get numb and tingly feet. I weigh around 155, ride in bike-specific shoes on platform pedals. Couple of things that have helped me. Be sure my shoes are sized large enough to accommodate some swelling as I ride. Laces are not too tight. Changing the position of my feet on the pedals even a little bit helps. I usually don't have a problem until 15-20 miles. If all else fails, I get off and walk 25-30 yards.
