In order to determine the appropriate size, you need to measure your foot length in centimeters. To do this, put on your socks, stand on a piece of paper and circle your "footprints" with a pencil, or draw lines like shown on the image below. Now measure the length from the longest finger (could be the first or the second finger) to the heel. For right-handers left foot should be slightly longer than the right one, for left-handers, respectively, on the contrary. To determine the size, use the highest length. If your foot length is between two sizes, we recommend to choose a smaller size. For instance, if your foot length is 27.5 cm, the recommended size will be 42. For footwear, that will be worn on warm socks, add 0.5-1 cm.
