Boot size & blade length

1 Feb 2022
by Diederik Hol

Want to know the correct length for your blades? At Cádomotus we advise you to use your body height, and not your shoe size, as a starting point to determine the correct length of your blades.


When you buy a bike, you wouldn’t even think to determine the size of your bike by your shoe size. But in skating, it happens all the time. Even though scientific research shows that the correlation between body height and his or her shoe size is under 60 percent. There is a correlation, but not a very strong one. This is why we also use body height to determine the correct length of the blades.

Correlation between foot length and body height

Without feet, you would fall over. Everybody knows that. Your feet are supporting your body and are necessary to keep your balance. The muscles, tendons and ligaments in your feet are helping your body to maintain a balance. Your toes are helping to keep that balance before you even start to move, like in walking and running. It is simple: the taller you are, the more support you need. Tall people have in 60 percent of all cases bigger feet, and a bigger shoe size.

Your ideal blade length

It means that your shoe size does not always predict the amount of support you need on the ice. Your shoe size says something, but not everything. If you take your body height into consideration, you will end up with a better-fitting pair of skates. This will help you with your technique, balance, and coordination and will allow you to become a better skater. 

Below you’ll find a table you can use as a guideline for finding the right blade length. The foot length in the third column is calculated according to a medical-scientific formula, using body height in the second column.
