📏Seba Light Speed Size Chart
The Seba Light Speed boot is sold in single EU sizes. Measure your foot length in cm and match it to the EU row below. The Shell column is the shared shell size, useful for replacement parts.
How to measure: Place a sheet of paper against a wall on a hard floor. Stand with your heel to the wall, mark your longest toe and measure the distance in cm — match that to the chart.

| 23.5 | 37 | #3 |
| 24.5 | 38 | #4 |
| 25.5 | 39 | #5 |
| 26 | 40 | #6 |
| 26.5 | 41 | #7 |
| 27 | 42 | #7 |
| 27.5 | 43 | #8 |

Model Cut
Normal — suits all feet. Match your foot length in cm to the EU row above.
Fitting for COMFORT
Buy your exact size.
Fitting for PERFORMANCE
Size down one for a snug, responsive fit.
Shell
Shared across neighbouring sizes (see the Shell column) — replacement shells follow this grouping.
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 — 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 moving around freely, or the heel lifting after tightening.
