Layering system, sure-footedness, bonking: the Hiking ABC explains every key term in plain, friendly language – perfect before you dive into our guides.
## Introduction Reading a hiking guide and tripping over words like "Zwiebelprinzip" (layering system), "Trittsicherheit" (sure-footedness), or "Hungerast" (bonking) and wondering what they actually mean? That happens to every beginner — hiking has its own language, and it's best to learn it BEFORE your first tour, not halfway up at 1,800 meters. Here are all the terms that actually show up in our hiking guides, explained simply and casually. After this, you'll understand every guide right away without constantly looking things up.
## Gear & Clothing Layering system (Zwiebelprinzip, literally "onion principle"): Instead of one thick jacket, you wear several thin layers on top of each other — like an onion. Getting warm? Take a layer off. Cold at the summit? Put it back on. Sounds simple, but it's THE foundation of hiking clothing.
Base layer (Base-Layer): The layer directly on your skin, usually merino wool or synthetic. Its only job: wick sweat away from your body before you get cold and clammy. Cotton is a no-go here — it soaks up sweat like a sponge and chills you fast.
Mid layer (Mid-Layer): Your warming middle layer, typically fleece or a light down or Primaloft jacket. It traps the air your body has warmed up — working like a thermos.
Hardshell: Your wind- and waterproof rain jacket, often with a membrane like Gore-Tex. Mandatory gear on EVERY tour, even under a blue sky in the valley — weather in the mountains can turn within minutes.
Membrane (e.g. Gore-Tex/GTX): The technical layer in a jacket or boot that keeps water out from the outside while letting sweat vapor escape from the inside. That's how you stay dry in the rain WITHOUT soaking in your own sweat.
Footwear categories (Wanderstiefel, Halbschuh, Trailrunner): Different terrain calls for different boots. A high-cut hiking boot supports your ankle on uneven ground, a low-cut shoe is fine on flat, well-built trails, and a trail runner is light and fast but offers no ankle protection. Rule of thumb: the steeper and rockier the terrain, the taller and stiffer the boot.
Trekking poles (Trekkingstöcke, Teleskopstöcke): Adjustable poles that take load off your knees, especially on descents, and give you extra stability on tricky sections. Not mandatory, but your knees will thank you.
Bivy sack (Biwaksack): A compact, usually orange emergency shelter made of tear-resistant material that you pull over yourself in a pinch to avoid hypothermia. Always belongs in your pack, even though you hopefully never need it — like a spare tire in your car.
## Walking Technique & Sure-Footedness Sure-footedness (Trittsicherheit): The ability to move safely and confidently over uneven, sometimes unstable terrain without losing your balance. Sounds abstract, but it just means placing every step deliberately and under control instead of just stomping ahead.
Full sole contact (voller Sohlenstand): Placing your foot down with the whole sole, not just the edge. That increases the contact area and therefore the friction with the ground — like a wide car tire that grips better than a narrow one.
Proprioception (Propriozeption): Your body's sense of where it is in space — basically, feeling exactly where your foot is without looking. You can train this at home, for example by standing on one leg while brushing your teeth.
Leaning into the slope (Innenlage): The — wrong — reflex to lean protectively toward the mountainside when crossing a steep, narrow path. Sounds logical, but it's dangerous: it puts less weight vertically onto your soles, which reduces friction and makes you more likely to slip. Stay upright instead — you'll actually have more grip.
Leaning back (Rückenlage): The classic beginner mistake on descents — you lean backward because it feels safer. It's actually the opposite: your center of gravity ends up behind your heels, and you're more likely to slip forward. Bend your knees slightly, lean your upper body slightly forward, and you'll stay centered.
## Planning, Weather & Safety Elevation gain (Höhenmeter): The height difference you climb on a tour — more important for how hard it feels than the raw distance. 5 kilometers with 600 meters of elevation gain is tougher than a flat 10-kilometer walk. Rule of thumb for the ascent: roughly 300 to 400 meters of elevation gain per hour.
Sudden weather change (Wettersturz): An abrupt, often dramatic shift in mountain weather, usually bringing falling temperatures, wind, and precipitation. Can turn a sunny afternoon into a dangerous situation within minutes — which is why your rain jacket ALWAYS belongs in your pack, no matter how blue the sky looks in the valley.
Bonking (Hungerast): The sudden performance crash when your carbohydrate stores run empty — you go weak, shaky, and unfocused almost instantly. The fix is simple: eat small snacks regularly before hunger even sets in.
Stop-or-go principle (Stop-or-Go-Prinzip): The ongoing decision on a tour of whether to keep going or turn back, based on weather, fitness, and terrain. Turning back is never a failure — it's the most important life insurance you have in the mountains.
Accident chain (Unfallsuppe, literally "accident soup"): A term from mountain safety research for the chain reaction that leads to an accident — rarely ONE single mistake, but a combination of poor planning, wrong gear, and bad decisions on the trail. Good preparation defuses this chain before it "boils over."
GPS track / offline map (GPS-Track / Offline-Karte): A digital route recording you download to your phone beforehand (e.g. via Komoot or Outdooractive) so you can navigate even without cell signal. Always download it BEFORE the tour, not at the trailhead once you've already lost reception.
## Pro Tip Remember this word pair: "sole, center of gravity." Almost every walking-technique question in hiking comes back to whether you're placing your full sole down and keeping your center of gravity vertically over your feet — uphill, downhill, and on traverses. Whenever a later guide gets more complicated, come back to this one anchor.
## FAQ ### What is the layering system (Zwiebelprinzip) in hiking? The layering system means wearing several thin clothing layers instead of one thick jacket — typically a base layer, mid layer, and hardshell. That lets you flexibly open or remove a layer instead of sweating on the climb or freezing at the summit.
### What does sure-footedness (Trittsicherheit) mean in hiking? Sure-footedness is the ability to move safely and deliberately over uneven, sometimes unstable terrain without losing your balance. It combines balance, muscle strength, coordination, and proprioception, and you can train it with targeted balance exercises.
### What is bonking (Hungerast) while hiking? Bonking is the sudden performance crash that hits when your carbohydrate stores run completely empty on a hike — you become weak, shaky, and unfocused. Prevention is simple: eat small, energy-dense snacks like nuts or dried fruit regularly, before hunger even sets in.
### How many meters of elevation gain can a beginner do per hour? A rough rule of thumb is 300 to 400 meters of elevation gain per hour for an averagely fit beginner. When planning your tour, add generous buffer time for food, photo, and rest breaks too — they add up more than you'd expect.
### What is an "accident chain" (Unfallsuppe) in hiking? "Unfallsuppe" is a mountain-safety-research term for the chain of several small mistakes that together lead to a serious accident — for example, poor planning plus the wrong footwear plus leaving the marked trail. Good preparation defuses exactly this chain before it "boils over."
