As well as length, skis vary in width and flexibility. If you’re planning on sticking to designated pistes, your skis will be shorter and have a narrow blade. If you’re a beginner, you should opt for skis that are flexible and light, making them more forgiving if you make a mistake and less physically demanding to use. The better your ability, the more rigid a ski you’ll need. If you’re more advanced as a skier and heading off piste, your skis will be longer and have a wider blade to give you better lift in powder.
