Cleat Fore-Aft Calculator

The cleat centre wants to sit under the first and fifth metatarsal heads. From EU size this estimates foot length, then marks 35% of that length back from the toe.

Inputs

Shoe size (EU)

Results

Estimated foot length: 11 in
Cleat centre from toe: 4 in
Cleat centre from heel: 7 in

How the number is made

Foot length mm = 265 + (EU − 42) × 6.67. Cleat from the toe ≈ 35% of that length. From the heel ≈ 65%. Mark the shoe, then look at knee tracking on the bike.

Shoe last and insole thickness move the real metatarsal. Use this as the first mark, not the last.

Questions

Three-bolt or two-bolt?

The mark is the same. The slot length differs, so a small shoe may not reach this fore-aft on every sole.

Why not the middle of the shoe?

The ball of the foot sits forward of halfway. A mid-shoe cleat usually feels like pedalling with the arch.

Is the cleat mark 35 percent from the toe?

Yes. The estimate sits 35 percent of foot length back from the toe, which is 65 percent forward from the heel.
