The Complete Handbook of Bicycle Cleat Covers

Chapter 1: Understanding Bicycle Cleat Covers

A bicycle cleat cover is a small, removable guard that fits over the metal or plastic cleat protruding from the sole of a cycling shoe. It is a deceptively simple accessory that solves a very specific set of problems created by the design of clipless pedal systems. These systems, which lock the shoe to the pedal for efficient power transfer, leave the cleat exposed when you are off the bike. This exposure is the root cause of several daily frustrations for cyclists, and the cleat cover exists to mitigate all of them.

Consider the mechanical reality of the cleat itself. A two-bolt mountain bike cleat, the SPD style, is a small metal mechanism, typically around 30 millimeters by 30 millimeters, that protrudes 5 to 8 millimeters from the shoe sole. A three-bolt road cleat is even larger, often extending more than a centimeter past the sole. These are precision parts built to engage with a pedal mechanism with tight tolerances. They are not designed to be walked on. Walking on a hard surface with a cleat does several kinds of damage simultaneously. It grinds down the engagement surfaces of the cleat, rounding the edges that must click into the pedal spring mechanism. Over time, this wear leads to a phenomenon called "click in and out" failure, where the cleat no longer seats firmly into the pedal because the metal lip is worn smooth. This reduces pedaling efficiency and, more dangerously, can cause an unexpected
