Mountaineering boots should be comfortable, but also robust and offer sufficient grip on different terrain – so the requirements are high. However, not all mountaineering boots are the same, as a distinction is made between hiking boots and mountaineering boots in categories A to D. Don’t worry, with our guide you’ll find the perfect companion for your mountain adventures.
What is the difference between mountaineering boots and hiking boots?
Hiking and mountaineering are popular leisure activities, but they place different demands on equipment. Hiking and mountaineering boots may look similar at first glance, but they have specific features that optimize them for the respective area of use.
> Hiking boots are suitable for easy hikes on well-maintained paths, are lighter, breathable and have a more flexible sole that rolls well.
> Mountaineering boots are designed for demanding terrain and alpine tours. They are more robust and stable to withstand demanding terrain, have stiffer soles and are mainly made of water-repellent materials.

What categories are there for mountaineering boots?
Anyone who deals with the subject of mountaineering boots will sooner or later come across the classification of boots into A, B, C and D boots. There are also intermediate types. But what do these classifications actually mean?
Using the categories from A to D, mountain sports enthusiasts can see for which terrain a pair of shoes is best suited – and where it will reach its limits. Of course, personal fitness (especially in the foot muscles) and personal preferences also play a role in the selection process.
Mountaineering boots category A
Approach shoes are specially designed for the path through rough terrain to climbing rocks and combine the features of hiking and climbing shoes. Thanks to their grippy soles, robust materials and precise lacing, they offer optimum grip and stability – even on rock and scree.

What are crampon-compatible mountaineering boots?
Crampon-proof mountaineering boots are indispensable for ambitious mountaineers as soon as snow fields, glacier crossings or steep passages in alpine terrain need to be tackled. Unlike normal hiking boots, they have a special sole that allows the use of crampons. This sole is significantly stiffer and made from robust materials to withstand the strain of crampon climbing.

The right fit: do hiking boots need to be one size bigger?
The right hiking boot is the be-all and end-all for an enjoyable hiking experience. But how do you find the perfect shoe that also fits comfortably on long tours?
The shoe size is only a guide
- Feet change during the course of the day – it is therefore advisable to try them on in the afternoon.
- Always wear hiking boots with the right hiking socks
- Click here for our socks guide
- Toes should touch at the front: There should be a finger’s width of space at the back of the heel (rule of thumb: 1 cm).
- Remove the insole and place your foot on it to check the size.
Check the heel fit: The heel must not slide upwards or sideways.
Further tips for suitable hiking boots
- Lacing: Lace the shoe tightly in the forefoot area and leave it a little looser in the upper area.
- Try out different models and brands: Feet are individual, try different models and brands to find the perfect shoe.
- Specialist advice in the outdoor store: At Sport Conrad in Garmisch-Partenkirchen and in Penzberg, we use the so-called Foot Scanner to determine your exact foot shape, expose problem areas and can thus select the right mountaineering boot.

THE AGONY OF CHOICE: WHICH MATERIAL IS THE RIGHT ONE FOR MOUNTAINeering BOOTS?
Leather or membrane? This question often arises when buying new shoes. Both materials have advantages and disadvantages that need to be weighed up.
Gore-Tex® membrane in mountaineering boots: advantages and disadvantages for multi-day tours and alpine terrain
Waterproof and breathable: mountaineering boots with a Gore-Tex® membrane are ideal for multi-day tours and alpine terrain with snow fields. The membrane offers optimum protection against moisture and is breathable at the same time.
Natural foot climate: Full leather shoes offer pleasant comfort and excellent breathability in summer temperatures. In heavy rain, however, the leather soaks up moisture, becomes heavy and dries slowly.
The right choice:
- Membrane shoes:
- Multi-day tours
- Alpine terrain
- Snow fields
- High risk of rain
- Leather shoes:
- Summer temperatures
- Short tours
- Low risk of rain
