3. Waist Width
From 75 to 85 mm: choose this width if you want performance skis. They are usually very light and perfect for fast and technical climbs, but they are less stable on the descent.
From 85 to 95 mm: this waist width is a good compromise between climbing and descending on variable terrain.
More than 95 mm: this width is ideal for powder days and for skiers who favor the pleasure of the descent over the ascent. The wider the waist width, the more your skis will perform in powder, but they will be less maneuverable on hard snow.
4. The weight of the skis
The weight of your skis should correspond to the type of skiing you want to practice as well as the rest of your equipment. For example, if you opt for light skis, make sure the rest of your equipment is also light for optimal performance.
Keep in mind that the lighter the skis, the easier they will be to climb, but they will be less stable on the descent.
