Size chart

Sizing notes

To use La Sportiva's size chart to fit mountain boots, find the European size that corresponds to your American size and then add one half size. When trying on boots, make sure to bring the socks you would normally wear and any orthotics or custom footbeds you use. La Sportiva's shoes are handmade, and you can experience minor variations in sizing from pair to pair in a given size. What you’re looking for is the size that holds your toes ever so slightly away from the front of the boot while the lacing system is snug across the top of your arch. To check the length, 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. The fit across the top of your arch is the single most important factor. If the lacing system here does not hold your foot in place, the boot will not be stable on your foot while you walk. If the boot is too short, your toes will get smashed walking down hill. Too long and your heel will slide up and down and give you blisters.
