This is a replacement cleat set for Shimano SPD pedals. It features a single - directional release design. You can easily unclip your shoe by simply rotating your heel outwards. The set includes cleat bolts and plates. Note that these cleats are not compatible with PD - M858 pedals.

Using this Shimano cleat set is easy. First, attach the cleats to your cycling shoes using the included cleat bolts and plates. When you're on the pedals, to unclip, just rotate your heel outwards as the single - directional release design allows. As for maintenance, regularly check the cleats for wear and tear. If the cleats are too worn, they might not work properly. Also, keep them clean to ensure smooth operation. And remember, these cleats won't work with PD - M858 pedals, so don't try to use them together.
