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.

The La Sportiva Nepal Cube is the best of a long line of mountain boots. Our testing team thinks of this boot like the Toyota Tacoma of mountain boots; it's not the fastest or lightest or the highest tech, but it will get you there. If it fits your foot, this is a good quiver-of-one boot. For those of you who can't wait for summer to be over, and find yourselves watching Steve House solo Repentance and Remission on YouTube over and over, this is your boot.
When I put on the Nepal Cubes the next morning, the boots were surprisingly comfortable despite them sitting in a freezing tent vestibule all night. My fellow guides in three-season boots complained bitterly all morning as their feet slowly warmed. We tackled Joffre's "S. Ridge" route and I found my Cubes to jam and edge easily as we moved up some 5.8 pitches where, again, the lighter weight was notable. I was very pleased with the Cube's ability to transition from rock, to ice, to snow, and perform well regardless of the material underfoot. A crisp, new sole doesn't hurt, either, of course. The only situations I felt insecure in the Cubes were on delicate or very smooth rock slabs where these boots were completely unable to smear because of their honeycomb carbon fiber insole (read: very stiff). But that stiff construction is what enables Sportiva to make a lighter and more insulated boot, and those features easily compensated for the momentary struggles.
