📏RB Apex Size Chart
The Rollerblade Apex is an adjustable junior skate — each size extends across an EU range to grow with your child. Measure your child’s foot length in cm and match it to the adjustable range below; the Size (cm) column is the skate size.
How to measure: Place your child’s foot flat against a wall on a sheet of A4 paper. Draw a line at the tip of the longest toe and measure the distance to the edge of the paper — that cm value is the size to match.
| Foot (cm) | EU | US (Kids) | UK | Size (cm) |
|---|---|---|---|---|
| 18.1 – 21.0 | 29 – 32 | 12J – 1 | 11J – 13J | 18.5 – 20.5 |
| 20.6 – 24.0 | 33 – 36.5 | 2 – 5 | 1 – 4 | 21.0 – 23.0 |
| 22.6 – 26.0 | 37 – 40 | 5.5 – 7.5 | 4.5 – 6.5 | 23.5 – 25.5 |
Width Guide
Rollerblade Apex skates are a Medium width.
Adjustable Sizing
Each size extends across an EU range via the adjustable shell. Match your child’s foot length in cm to the range above.
Fitting for COMFORT
Upsize to make full use of all sizes — e.g. an EU30 foot takes the EU33–36.5 range, not EU29–32.
Fitting for PERFORMANCE
Upsize and add a thick insole to fill the space.
Adjustable Shell
Push-button adjustable shell extends across the size range — lengthen it as the foot grows, so one skate lasts several sizes.
Liner
Rollerblade junior liner — it breaks in and moulds to the foot.
Insoles
Add an insole to fill space if you upsize; remove a layer as the foot grows.
✓ How it should feel
A snug fit with toes just touching or reaching the front. Set the shell larger for growing room and shorten it as the foot grows.
✗ How it should NOT feel
Toes curling up, the heel lifting once buckled, or the foot sliding around even at the smallest setting — size up a range.
