Some shoes have especially deep wells in their soles for housing the threads into which you fasten your pedal cleat screws. Speedplay is aware of this, which is why they offer these 4 x 15mm bolts for mounting Zero, X Series, and Light Action cleats. One packet of these screws is enough for two cleats. Please note that all you're purchasing here are screws -- not cleats as well. If you need replacement cleats, you'll need to purchase those separately.
Please Note: Due to manufacturer restrictions, we are unable to ship Speedplay products outside the United States.
