We round the shoe size up. 28.5 cm gives 45 and not 44.5 — a little extra space gives better comfort, room for thicker socks and warmer feet.
How do you measure school length?
Place a sheet of paper against the wall, place your heel against the wall and draw a line in front of your longest toe. Measure the length in millimeters. Adjust ±5 mm depending on how thick your socks are and how tight you like the fit.

Important about shoe sizes
The tables below are based on the manufacturers' own size guides and give a good indication. However, sizes can vary slightly between brands and model years, so use them as a guide. If in doubt, choose one size up: slightly larger shoes allow for thicker socks or an extra insole, and keep your foot warmer because it is not squeezed.

Frequently asked questions
Should cross-country skiing boots fit snugly or loosely?
They should fit snugly around the heel and instep, but the toes need to have room to move. A shoe that is too tight will cause cold feet because blood flow is reduced.
Are cross-country shoes the same size as regular shoes?
Usually yes, but it varies between brands. Measure your foot in cm and use the size chart instead of your usual size.
What is mondopoint?
Mondopoint is the foot length in millimeters, and is the international standard for ski boots. 270 mondopoint means 27.0 cm foot length.
Should I choose a size up?
If you are between two sizes, choose the larger size. This allows for thicker socks and warmer feet. For competition use, many people prefer the tightest fit possible.
