When going for a bike ride with the family or camping I wanted to make some platforms that press into the clipless pedals on my mountain bike so I don't need my mountain bike shoes. These work with shimano clipless pedals specifically designed for SLX but I have some SPD M20 and they press in and works for those as well. I am not using actual cleats they just press in with enough resistance to hold but pull straight off. So far I am really happy with how these work. I can ride bike with bare feet comfortably. Also there are some small holes in design for putting small screws into face for more grip on shoes.
