Skiing When choosing the size of ski boots, it is essential to base it on the actual foot size. It is important to select a size that fits perfectly according to the length of your foot, but for those who are not accustomed to skiing, it is advisable to choose a size that is 0.5 to 1 cm larger. This will increase comfort and reduce pressure on the feet. Choosing the right size of boots is a crucial factor that greatly affects the quality of the skiing experience.
