📏RB Microblade Size Chart
Rollerblade Microblade kids skates use an adjustable push-button shell that expands across 4–5 EU sizes per pair. Match your child’s foot length in cm (Mondo) to the row below — for kids who are growing, choose the size where their current foot sits in the lower half of the range.
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 below.
| Size | Foot (cm) | EU | US | UK |
|---|---|---|---|---|
| S | 17.5 – 20.5 | 28 – 32 | 11J – 1 | 10J – 13J |
| M | 21 – 23 | 33 – 36.5 | 2 – 5 | 1 – 4 |
| L | 23 – 26 | 36.5 – 40.5 | 5 – 8 | 4 – 7 |
Adjustable shell
The push-button shell expands across 4–5 EU sizes. Each bracket above (S/M/L) is one pair of skates that covers the whole range.
Fitting for COMFORT
Size up to make full use of the range. If your child is EU 32 today, buy M (33–36.5), not S (28–32) — they’ll grow into it.
Fitting for PERFORMANCE
Size up and add a thicker insole to take up the front gap while still leaving growth room.
Insoles
If the skate runs loose after sizing up, drop in 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
Extremely snug at the sides. Space at the toe area is fine — the child is growing. Toes touching or reaching the front is the best fit. Toes shouldn’t be pressed flat against the front of the skate.
✗ How it should NOT feel
Toes curling up. Heel lifting in the skate after buckles are tightened. Significant slop side-to-side at the ankle.
