📏USD Carbon Size Chart

The USD Carbon is a premium carbon-fibre aggressive boot, sold in single EU sizes. Measure your foot length in cm (Mondo) and match it to the EU row below. The US columns show Men’s and Women’s.

How to measure your foot

How to measure: Place your foot flat against a wall on a sheet of A4 paper. Draw a line at the tip of your longest toe and measure the distance to the edge of the paper — that cm value is the size to match.

Foot (cm) EU US (M) US (W) UK
25 39 7 8 6
25.8 40 7.5 8.5 6.5
26.4 41 8 9 7
27 42 9 10 8
27.7 43 10 11 9
28.4 44 10.5 9.5

Fitting for PERFORMANCE

Shell

A lightweight carbon-fibre aggressive boot — stiff and supportive for maximum power and control.

Liner

Every size has its own liner; it breaks in and moulds to the foot.

Insoles

A thinner insole adds about half a size of space inside the boot — e.g. a 42 becomes a 42.5.

✓ How it should feel

Wrapping with slight discomfort that softens and expands after 6–8 hours. Toes touching or reaching the end.

✗ How it should NOT feel

Toes curling up, the foot able to move around freely, or the heel lifting after tightening.
