📏RB Apex Size Chart
Find your Rollerblade Apex size. These are adjustable kids’ skates — each size spans several EU sizes and extends as the foot grows. Simple method: pick the range your child’s normal shoe size falls in. Detailed method: measure foot length in centimetres and match below. If the child measures at the top of a range and is still growing, choose the next size up for longer use.
How to measure: Stand on a hard floor with the heel against a wall and measure both feet heel-to-toe in centimetres; use the longer foot.
| Foot (cm) | EU | Size (cm) | US | UK |
|---|---|---|---|---|
| 18.1 – 21.0 | 29-32 | 18.5 – 20.5 | 12J-1 | 11J-13J |
| 20.6 – 24.0 | 33-36 | 21.0 – 23.0 | 2-5 | 1-4 |
| 22.6 – 26.0 | 37-40.5 | 23.5 – 25.5 | 5.5-7.5 | 4.5-6.5 |
How it adjusts
Each Apex size extends over several EU sizes — release the sizer under the toe and slide to the marked size, so one pair grows with the foot.
Skate prep
Remove all paper and plastic from the toe box before putting the skates on, then fasten the closure securely to lock the heel and ankle in place.
✓ How it should feel
Toes just short of the front with the closures fastened; room to extend a size or two as the foot grows.
✗ How it should NOT feel
Toes already at the end on the largest setting (size up), or the foot slides at the smallest setting (size down or add a thicker sock).
