Yuppers - and don't keep your feet so static, curl and flex the toes inside the shoes to keep the blood flowing in there. I've also noticed my feet can go numb when I'm climbing which means I'm "mashing" instead of spinning and pushing down way too hard on the clips. On long rides, I'll take my shoes off during my rest stops and walk around barefoot (or sockfoot).
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
