Crampons must match your boots. Strap-on crampons fit most flexible boots; hybrid (semi-automatic) crampons need a heel welt and suit stiffer B2 boots; automatic (step-in) crampons need toe and heel welts on rigid B3 boots. Very flexible B0 footwear is not for crampons. Ice axes certified to EN 13089 are Type 1 (B) for general mountaineering or Type 2 (T) for technical climbing.
Crampons that do not match the boot can pop off on a slope. Boot rating and binding type must agree.

Common questions
What are B ratings on mountaineering boots?
A stiffness rating from B0 (flexible, not for crampons) to B3 (rigid, with toe and heel welts for automatic crampons).
Can I use automatic crampons on any boot?
No. Automatic crampons need boots with toe and heel welts, usually B3.
What is the difference between a B and T ice axe?
Under EN 13089, Type 1 (B) axes suit general mountaineering; Type 2 (T) axes meet stronger requirements for technical climbing.
How long should my ice axe be?
Shorter axes are common today for general mountaineering; follow the maker's sizing guidance and your intended terrain.
