Yeah mine are worn out too. I find that with size 13 shoes/boots, the pedal is not big enough. I was thinking about getting a couple of pieces of diamond-plate and having them cut to make the actual pedals bigger too fit my feet but not be too big to cause an accidental directional change. I was thinking of taking off the tredle and welding the pieces on in place of the rubber feet. I'm glad you mentioned this because I was just looking at my pedals the other day and I kind of put into one of those "I'll deal with it" another day category. I guess I'll be getting to it!
