📏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.
