This is a great boot - lightweight and very comfortable right out of the box. The only area in which they did not measure up to my needs was cold weather. When I say cold I am talking single digits on either side of zero. For this I had to move up to the La Sportiva K4S boot. Similar in price (some places) but heavier and a longer break in period. If you plan on keeping your activities in over over 15 degrees F conditions the Makalu is all you need. Otherwise look at the K4S. Both made by the same Italian craftsmen at the foot of the Dolomite Mountain Range
