📏RB Nitro Size Chart
The Rollerblade Nitro comes in single EU sizes. Measure your foot length in cm and match it to the EU row below.
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.
