๐FR SLJ Size Chart
At its core, the FR SL J stands out with its 3-in-1 insole system, enabling each skate to expand by +2 sizes regardless of the starting size โ going beyond traditional adjustable skates for unmatched longevity and precise fit tuning over time. Measure your childโs foot length in cm and match it to the adjustable EU range below; the MP (Mondopoint) column is the most precise, and the EU range matches the variant to buy.
How to measure: Place your childโs 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 from the line to the edge of the paper โ that cm value is the size to match.

| 21 โ 22 | 33 โ 35 | 2 โ 4 | 1 โ 3 | 21.5 โ 22.5 |

| 22.5 โ 24 | 36 โ 38 | 4.5 โ 6 | 3.5 โ 5 | 23 โ 24.5 |
| 23.5 โ 25 | 37 โ 39 | 5 โ 7 | 4 โ 6 | 23.5 โ 25.5 |

Adjustable Sizing
Each size adjusts across a 3-size EU range via the 3-in-1 insole system (+2 sizes from the base). Match your childโs foot length in cm to the range above and buy that EU-range variant.
Fitting for COMFORT
Start at the smaller end with all insole layers in, then peel a layer as the foot grows.
Fitting for PERFORMANCE
Set the insole layers so the boot fits your childโs exact measured size for a snug, responsive slalom fit.
3-in-1 Insole System
Three stackable insole layers give a +2-size adjustment from the base size, regardless of the starting size โ peel a layer as the foot grows. The shell itself is fixed.
Frame & Mount
150ย mm mounting system (compatible with most 165ย mm frames) lowers the centre of gravity; the wheel setup evolves with foot size.
Liner
FR junior liner breaks in and moulds to the foot.
โ How it should feel
A snug fit with toes just touching or reaching the front. Add insole layers if there is extra room, and peel a layer as the foot grows.
โ How it should NOT feel
Toes curling up, the heel lifting once buckled, or the foot sliding around even with all insole layers in โ size up a range.
