Heel Pitch vs Heel Height: Why 70 mm Feels Like 90
Heel height is not what your foot feels. This explains heel pitch, how a platform cuts it, and how to measure the angle on a pair you already own.

A 90 mm heel with a 30 mm platform puts your foot at the same angle as a 60 mm heel with no platform. The number on the box is heel height; what your calf and the ball of your foot respond to is pitch, the angle of the footbed.
Height, pitch and platform are three different numbers
Heel height runs from the ground to the top of the heel at the back. Platform height is the sole thickness under the ball of the foot. Pitch, sometimes called effective heel height, is the net rise: heel height minus platform. The angle is that net rise divided by the horizontal heel-to-ball distance.
| Shoe | Heel height | Platform | Net rise | Pitch angle |
|---|---|---|---|---|
| Court pump | 90 mm | 0 mm | 90 mm | about 27° |
| Platform sandal | 120 mm | 30 mm | 90 mm | about 27° |
| Kitten heel | 45 mm | 0 mm | 45 mm | about 14° |
The pump and the sandal share a pitch despite 30 mm of difference in height, because the platform lifts the front of the foot by what it adds at the back.
Why 70 mm can feel like 90
The angle depends on footbed length as much as on rise. A short shoe has a shorter heel-to-ball distance, so the same heel height produces a steeper angle. A 70 mm heel over 140 mm gives roughly the pitch of a 90 mm heel over 180 mm.
Where the load goes
Raising the heel shifts weight forward. Against a flat shoe, a 50 mm heel increases forefoot pressure by roughly 75 per cent, and a 90 mm heel by more than 100 per cent, according to podiatric summaries. The foot also sits plantarflexed, which shortens the calf over time.
Shape changes how the same pitch feels. A block heel puts more material on the ground than a stiletto, reducing the ankle wobble the wearer must control, while a wedge fills the space under the arch and leaves a gentler footbed angle than the heel height suggests.
Measuring pitch on your own shoes
Measure the heel height vertically, the platform under the ball, and the horizontal heel-to-ball distance. Take heel height minus platform and divide by the distance, and you have a slope you can compare across shoes. It is a static model, since walking adds motion and cushioning, but it separates shoes with the same height label.
What to check in the toe box
Forward load pushes the foot forward in the shoe, so a high-pitch shoe needs vertical room as well as width. Toes bunched against a shallow toe box is a fit problem, not a break-in problem. Pair a steep shoe with the fit advice in wide-fit shoes, and check clearance with ankle boot shaft and calf fit before buying a heeled boot.
FAQ
- Is heel pitch the same as heel height?
- No. Heel height runs from the ground to the top of the heel. Pitch is the angle of the footbed, and a platform lowers it.
- Why does the same heel height feel different on two shoes?
- The geometry differs. Footbed length, platform thickness and heel shape all change the pitch angle and where your weight lands.
- How do I measure pitch at home?
- Measure heel height, platform thickness under the ball, and the horizontal heel-to-ball distance, then divide heel height minus platform by that distance.
