I have a pair of those and a pair of the Shimano Ultegra SPD-SL pedals in the garage and they'll never see one of my bikes again. I rode with them all last summer but I hated walking in them, they were harder to unclip in emergency mode and they resulted in the worse accident I've had on a bike in quite a few years. I thought it would be safer for these old bones if I went back to the SPD pedals.
