📏New USD Sway w Prime Liner Size Chart
The USD Sway fitted with the MyFit Prime liner. Each shell covers a small 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.
| Foot (cm) | EU | US (M) | US (W) | UK |
|---|---|---|---|---|
| 23.6 – 24.2 | 37 – 38 | 5.5 – 6 | 6.5 – 7 | 4.5 – 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 |
| 27.2 – 27.5 | 42.5 – 43 | 9.5 – 10 | 10.5 | 8.5 – 9 |
| 28.2 – 28.9 | 44 – 45 | 10.5 – 11 | — | 9.5 – 10 |
| 29.6 – 30.3 | 46 – 47 | 12 – 12.5 | — | 11 – 11.5 |
Width Guide
With the Prime liner the USD Sway is a Medium width.
Width
With the Prime liner this set-up is a Medium width (see the Width Guide above). Each shell covers a small EU bracket; round up if you fall between brackets.
Fitting for COMFORT
Buy one size up, or round up if you fall between sizes.
Fitting for PERFORMANCE
Buy your exact size, or round down between sizes for a snugger fit.
Shell
USD Sway aggressive hard shell — each shell covers a small (1–2 size) EU bracket (dual sizing); the liner and insole fine-tune the fit.
Liner
MyFit Prime liner — a premium, plush, heat-mouldable liner with extra cushioning for comfort and precision.
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.
