I've been riding stock pedals and wearing some old Nike running shoes. Probably not ideal, but it works for now. I don't know the first thing about cycling shoes and pedals with clips and all that. I've never had any problems with feet slipping... but I do have big feet and they seems to be hanging off the sides of the pedals all the time anyway. Can this situation be improved on? Would it really make a difference? I'm a little short on cash most of the time... this is probably my lowest priority, unless there is a real difference to be made. Advice/suggestions?
