Basics
Familiarize yourself with the basic vocabulary of snow and avalanche awareness. See EAWS glossary. Pointed turns: First find as flat a stance as possible, followed by a kick turn - give the second ski a strong push when turning!
Track rather flat, but with a regular gradient and with foresight - plan for large rocks along the way and avoid them, do not head straight for them. Always track according to the avalanche situation. If the avalanche and snow conditions allow you to ski the entire slope: Use the entire width of the slope and avoid time-consuming and energy-consuming hairpin bends. Understand that the radius and width of a ski in a parallel turn has little influence on the size of the bends. The radius only affects the length of the turn when carving, not when sliding.
Always take your inner boots out of the shell to dry them. Otherwise you will trap moisture between the inner boot and the shell. Also remove insoles.
If you prefer to be out and about in the morning, take an afternoon nap instead. Understand that danger levels alone are just as useful for tour planning without additional information as touring skis without skins. Be happy to take something off a female companion - but never a backpack, shovel, avalanche transceiver and probe! (Editor's note: applies regardless of the gender of the companion.)
Keep in mind that ski lengths and widths have advantages and disadvantages: Basically, the wider and longer, the more track-stable and suitable for high speeds, but the more sluggish. Wide skis offer no advantages in fizzing firn conditions or hard snow conditions and disadvantages on the ascent, as it is much easier to "tip sideways" on steep slopes than with narrow skis. Narrower, shorter skis are much more maneuverable and more pleasant to ski on highly technical, narrow descents or slaloms in rocky slopes or mountain pines. 80mm medium-width skis are still a blessing for tours in little snow, piste tours and in hard or particularly technical downhill conditions.
The weight of the equipment has less influence on the effort required on the ascent than the maneuverability of the equipment. Unfortunately, weight and maneuverability are very often closely linked due to the design. Extra-wide skis are less strenuous for long ascents because of their higher weight - more because of the significantly larger skin surface and the resulting braking effect. In addition, they no longer fit into every ascent track and you can displace a lot of snow again under your own steam.
Use merino underwear. Because they are so infinitely comfortable on the skin and don't start to stink. Be skeptical of new material on the market and only buy it after one or two seasons. Remember once and for all that the most interesting part of winter alpine and high alpine touring takes place between March and June, not between December and February.
