Why wax cross-country skis?
Cross-country skiing is above all a gliding sport, so you must maintain the base of your skis to have the most fun on the slopes.
Waxing reduces grip (suction cup effect) and improves glide, optimising the compatibility of your ski base with the characteristics of the snow (air temperature, snow quality, etc.).
You can maintain your skis yourself or make an appointment with a professional at your workshop.
