How to find your skate size

The best way to determine your skate size is to measure your feet (both!) and write down the millimeters. See the image below for instructions, click for a bigger version.
Now you know how long both your feet are.

With this info you can check against the size chart of the skate of your choice. Keep in mind, no size chart is perfect, sizing of one brand or boot might be different from another brand or boot. And keep in mind your own preference regarding fit. Some like it tight, some like it (a little) more loose. Scroll further down for the size charts of specific brands.
