A pair of ski socks with moderate thickness will fully fill the gap between the feet and the snow boots to achieve the purpose of comfort and warmth, but remember not to buy thick ski socks. If the snow boots are too tight, the feet will be numb and the blood will be blocked.

　　2, warm and sweat-wicking clothes

　　A truly warm and sweat-wicking ski suit is necessary. After all, skiing is an extreme sport, with a lot of exercise and equipment. All needs are based on lightness, thinness and warmth. Forget the ordinary jersey and long pants. If the budget is limited, you can also have ultra-thin thermal underwear. Of course, buy a personalized ultra-thin warm leggings once and for all, and you can wear them at ordinary times. There is no need to go to the ski shop to spend more money. Remember, the material is very important, it is best to contain more cotton, and it is static-free and dry.

　　3. Grab cashmere pants

　　Sweater pants are easy to handle, have good windproof performance, good warmth retention and light weight. Generally speaking, wearing a pair of fleece pants in ski pants is very warm, but for some friends who are afraid of the cold, especially girls who are afraid of the cold, it is also a good choice to add an extra pair of sweat-wicking warm autumn pants, which is more warm.
