Alpine boots are required by those whose adventures take them well and truly above the snow line. 

Warmth
It’s essential the boot is able to keep feet warm for prolonged periods above the snowline. Warmth is achieved through a combination of insulation, upper material and a waterproof/breathable lining.

Uppers
Some boots have one-piece leather uppers but there are also multi-panel synthetic/leather options. The thickness of the upper should be between 2-3mm.

Fit
Perfection is crucial – these boots are so stiff, pressure points will not go away with use. Ensure enough wriggle room to keep blood flowing to the toes – helpful to prevent frostnip. The heel needs to be secure.

Stiffness
The shank is commonly made from nylon, fibreglass or Kevlar and has little or no flex over the length or width of the boot. This provides a stable platform in rugged terrain and while climbing, but will make the boots difficult to use on flat terrain.

Crampon compatibility
If the boot flexes lengthways or sideways, a flexible crampon with straps front and back should be used. Technical boots sometimes have a welt at the front for crampons with front and back clips.

Rand
A full rand running around the base of the upper protects the boot from ice, scree and moraine.
