📏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

Model Cut

Normal — suits all feet. Match your foot length in cm to the EU bracket above.

Fitting for COMFORT

Buy one size up.

Fitting for PERFORMANCE

Buy your exact size for a snug, locked-in aggressive fit.

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.
