Tips: La Sportiva recommends that you add one 1/2 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.

As I got the boots late in the season I’ve only been able to put 12 days of hiking, mountaineering and scrambling on them to date. Not enough time to wear them out and provide a detailed durability assessment but I can predict how they’ll perform based on what I’ve seen so far. That being said, the abrasion resistant fabric on the uppers has stood up amazingly well and shows almost no wear.
Considering these boots were designed for three-season use, I was a bit apprehensive about taking them out in August, which is peak summer season in the Colorado Rockies. To my surprise the Gore-Tex membrane did an excellent job at breathing, allowing my feet to remain comfortable while I hiked out in the blistering heat of lower elevations. Likewise, the boot remained warm in the cold mornings at higher elevations, even when I wasn't actively moving around. One morning I spent a few hours photographing time-lapses in a biting September wind at 13,400 feet and experienced no discomfort! After thousands of feet of snow climbing in soft, soggy slush, numerous rainstorms and river crossings, I am confident in the waterproof membrane of these boots.
