The cleat is the only contact point between foot and pedal — it decides where your foot sits on the pedal axle and at what angle. A cleat that's off by a few millimetres is one of the most common causes of knee pain, calf cramps, forefoot numbness ("hot foot") and Achilles tendon irritation. There are three axes to set: fore/aft, side-to-side and rotation.
The starting point: the first metatarsal head (the bony bump at the ball of the foot, MTP1) sits over or slightly ahead of the pedal axle. More precisely, the pedal axle sits about 5–10 mm behind that point.
| Cleat position | Effect |
|---|---|
| Ball directly over the axle | Classic standard, lots of drive from the ankle |
| Cleat further back (axle toward mid-foot) | Less calf work, calmer foot — helps with calf cramps, "hot foot" and Achilles issues |
| Cleat too far forward | Heavy calf load, forefoot numbness, unsteady pedalling |
For large feet (roughly EU 44 and up) and for long distances, the rearward position tends to help. Note: moving the cleat back effectively lengthens the leg through the stroke — afterwards, re-check saddle height and drop it 2–4 mm.
The lateral cleat position moves the heel inward or outward. Goal: the knee tracks straight over the foot through the stroke, without drifting in or out.
Rule of thumb: first give the heels as much clearance as needed, then correct in 1 mm steps. If you need a very wide stance, the cleat alone won't get you there — longer pedal axles or spacers do.
Most people don't stand with perfectly parallel feet. Cleat rotation sets the foot angle to match your natural stance (heels slightly in or out). Twisted the wrong way, it forces the knee onto an unnatural path — typically causing pain on the inside or outside of the knee.
Float is the released rotational angle (0°, 4.5° or 6–9° depending on the system). Some float (4.5–6°) gives the knee room to move and forgives small setup errors. Only ride fixed 0° cleats with carefully measured rotation.
| Symptom | Check |
|---|---|
| Pain at the front of the knee | Saddle too low or cleat too far forward — also check saddle height |
| Pain on the inside of the knee | Foot too far out / rotation too much "heels in" |
| Pain on the outside of the knee | Foot too far in / rotation too much "heels out", too little float |
| Calf cramps, irritated Achilles tendon | Cleat too far forward → slide it back |
| Numbness / burning in the forefoot | Cleat too far forward, shoe too tight, or saddle too far forward |
| Knee visibly collapses inward through the stroke | Stance too narrow → slide the cleat inward |
Set your phone up side-on and film a few crank revolutions at a normal cadence. The analysis measures your ankle and knee angle across the whole stroke and flags left–right asymmetries — a clear side difference in knee angle often points to skewed cleat rotation. Stance width itself is best judged with a second video from the front.
