The Heel Fat Pad Explained

In brief: The heel fat pad is the thick layer of cushioning fat beneath the heel bone that absorbs impact every time the heel lands. It is the body's own shock absorber for the rearfoot, and it works alongside a shoe's heel cushioning to soften landings.

What is the heel fat pad?

The heel fat pad is a dense layer of specialised fat sitting directly under the heel bone. It is structured into small chambers that act like built-in cushioning, spreading the force of each heel landing.

Why it matters

The heel fat pad is the body's natural shock absorber for the rearfoot. It takes the first hit when the heel lands and protects the bone above it, working together with the cushioning in a shoe.

How it works

When the heel strikes, the fat pad compresses and spreads the impact across a wider area before springing back. This reduces the peak force passing into the heel bone and up the leg.

What to look for

Heel cushioning in a shoe supports the fat pad, which can thin gradually with age and high mileage. A well-cushioned, secure heel helps keep landings comfortable, especially on hard surfaces.
