📏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 |
| 24.2 | 38 | 7 / 6 | 5 | 5 |

Width

Fitting for COMFORT
Round up a size and follow the chart for a relaxed fit.
Fitting for PERFORMANCE

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.
Size Chart Disclaimer. This chart reflects measurements supplied by Chaya. The Derby Ruby ships in single sizes EU 36–46 (EU 46 follows the same plate/sizing step); the Plate column shows the matching plate size. We cannot be held responsible for incorrect size purchases — when in doubt, message us before ordering.
Shipping is calculated at checkout based on your order. We ship with FedEx Express — fast, fully tracked, door to door.
Import duties & taxes, if any, can be prepaid in your cart, so there is nothing to pay when your order arrives in Thailand. If you choose not to prepay, they are payable to customs on arrival.
Hand-built skates can carry a few minor cosmetic marks and may need a short break-in — none of it affects performance or safety. See exactly what’s normal →
