Every step has to be thought through twice. Hard ice forgives nothing and your crampons hold on just a few millimetres of front points. A long spell on the wall doesn't help either. You're freezing. Getting the blood flowing again before the next pitch takes a while. But your feet – they stay warm. The Gore-Tex Insulated Comfort membrane keeps them equally warm from dawn onwards. And the Schoeller Soft Shell outer reliably keeps all moisture out.

When you have to, you jam your foot into a crack. When there's nothing left to grab, you take a shortcut across the scree. Asolo Eiger XT EVO GV boots have to take a lot, so they have a tough rand all the way round, a hard-wearing Vibram Litebase sole and an upper closure with a waterproof zip.
