📏Chaya Derby Ruby Size Chart
Chaya Derby Ruby quad skates come in single EU sizes. Measure your foot length in cm (Mondo) and match it to the row below. The Plate column is the size of the skate’s plate. The US column shows Women’s / Men’s.
How to measure: Place a sheet of paper against a wall on a hard floor. Stand on it with your heel against the wall and mark the tip of your longest toe. Measure the distance in centimetres — that cm value is your size.
| Foot (cm) | EU | US (W/M) | UK | Plate |
|---|---|---|---|---|
| 22.9 | 36 | 5 / 4 | 3 | 3 |
| 23.6 | 37 | 6 / 5 | 4 | 4 |

Width
The Chaya Derby Ruby is a Medium width (see the Width Guide above). Match your foot length in cm (Mondo) to the EU row.
Fitting for COMFORT
Round up a size and follow the chart for a relaxed fit.
Fitting for PERFORMANCE
Round down a size for a snug fit with better control.
Boot
Chaya Ruby quad boot from the derby line — agile and supportive for park, jam and rhythm skating.
Plate
The plate (the chassis the wheels mount to) is sized to the boot — see the Plate column. Replacement plates and tuning follow this size.
Insoles
A thinner insole adds about half a size of space — e.g. a 42 becomes a 42.5.
✓ How it should feel
A snug fit with toes touching or reaching the end when new. Soft quad boots expand and widen more than hard or carbon boots as they break in.
✗ How it should NOT feel
Toes curling up, the foot moving around freely, or the heel lifting once laced.
