For boots: Add one half size to your street shoe size. You should be able to slip one finger behind your heel when you are standing up with the boot unlaced and your toes touching the front. If the boot is too short, your toes will get smashed walking downhill. Too long and your heel will slide up and down and give you blisters.

Just got my size 47.5 in the mail. They are mindblowingly small. I’m a 47 in nearly any other European manufacturer. I ordered a 48.5 hoping they will fit because I couldn’t find a 49. Similarly received a 48 in another La Sportiva boot at the same time and had to return due to overall small size. Order up folks. Otherwise the shoe looks and feels super high tech, beautifully made, and super lightweight. Had to remove a star for their very silly sizing.
