I understand the need to use a strap twist to avoid it shifting. However, the pad shown in post #9 is installed incorrectly. Frequently the pad is referred to as a buckle pad. But the pads don't do much to insulate the buckle from the shoe. In reality, it is a toe clip pad and it is properly installed on the long part of the clip and then the strap threaded through the strap hole and the slit in the pad. When a strap is properly installed, the buckle is typically kept as close to the pedal as possible in order to avoid issues with the buckle against the shoe.
