📏USD Aeon Size Chart
The USD Aeon is a classic aggressive inline skate. Each shell covers a 2-size EU bracket (dual sizing) — measure your foot length in cm (Mondo) and match it to the EU bracket below. The US columns show Men’s and Women’s.
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 |
|---|---|---|---|---|
| 22.9 – 24.2 | 36 – 38 | 5 – 6 | 6 – 7 | 4 – 5 |
| 24.8 – 25.5 | 39 – 40 | 7 – 7.5 | 8 – 8.5 | 6 – 6.5 |
| 26.1 – 26.8 | 41 – 42 | 8 – 9 | 9 – 10 | 7 – 8 |
| 27.5 – 28.2 | 43 – 44 | 10 – 10.5 | — | 9 – 9.5 |
| 28.9 – 29.6 | 45 – 46 | 11 – 12 | — | 10 – 11 |

Fitting for COMFORT

Shell
USD Aeon aggressive hard shell — each shell covers a 2-size EU bracket (dual sizing); the liner and insole fine-tune the fit.
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.
