📏USD Transformer Size Chart
The USD Transformer is an adjustable aggressive kids skate — the push-button shell expands across 4 EU sizes per pair. Match your child’s foot length in cm (Mondo) to a bracket below; for growing kids, pick the bracket where their foot sits in the lower half.
How to measure: Place a sheet of paper against a wall on a hard floor. Stand the child on it with their heel against the wall and mark the tip of the longest toe. Measure the distance in centimetres — that cm value is the Mondo size to match against the chart.
| Foot (cm) | EU |
|---|---|
| 20.5 – 22.9 | 33 – 36 |
| 23.5 – 25.9 | 37 – 40 |
Adjustable shell
The push-button shell expands across 4 EU sizes. Each bracket above (33–36 / 37–40) is one pair that covers the whole range.
Fitting for COMFORT
Size up to make full use of the range. If your child is EU 36 today, buy the 37–40 bracket so there’s room to grow.
Fitting for PERFORMANCE
Aggressive skating wants a locked-in fit — buy the bracket their foot is in now and add a thicker insole to take up the gap.
Boot
Semi-hard aggressive boot built to take grinds while supporting growing ankles.
Insoles
If the skate runs loose after sizing up, add a regular shoe insole on top of the stock one to take up space. Remove it as your child’s foot grows.
✓ How it should feel
Snug at the sides with toes touching or reaching the front. A little toe room is fine — the child is growing.
✗ How it should NOT feel
Toes curling up. Heel lifting after the buckles are tightened. Foot sliding inside the boot on landings.
