📏USD Aeon w Basic Dual Liner Size Chart
The USD Aeon fitted with the MyFit Basic Dual Fit liner. Each shell covers a 2-size EU bracket — 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.

|---|---|---|---|---|
| 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 |

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
MyFit Basic Dual Fit liner — comfortable standard padding with a dual-fit shape; breaks in naturally with use.
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
A snug fit — toes touching or reaching the end and feeling tight when the skates are new is fine. As long as your toes are not curling up, the boot and liner expand and widen as they break in.
✗ How it should NOT feel
Toes curling up against the front, the foot sliding around, or the heel lifting after tightening — that means the skate is too small; size up.
