from what I hear people who only ride 2 or 3 miles at a time don't have any problems with them since that is not enough time for the seat cover to ass ****... I mean hurt you.
I really have no suggestions though. My butt hurts all the time on my bike, I figure it'll just go away once I lose some weight. After all, I weigh slightly over 300 pounds and to be honest, everything hurts.
