Optigrip® ja Nanogrip® -coated skies are the first waxless classic skies, wich won´t based on mechanical grip. The secret of simultanous glide and grip lies in the control of rest and glide friction in different conditions.
Functionality is a result of years of research and development including intense testing. In order to get grip the ski uses water layer between snow and ski surface. At rest position the surface will break the shape of water molecules, which creates very high friction and the ski will get the grip. In the glide phase the surface has characteristics that will decrease glide friction. Nanogrip and Optigrip skis work in every condition, but the function is optimal when water layer between snow and surface is substantial.
Waxless nanoski is ready for skiing straight from the shop, but in the beginning especially the glide properties are not optimal yet. The glide and grip properties will increase after short skiing. During this introduction period snow crystals will grind away extra surface. The nano particles get better touch with snow and water molecules which will increase both glide and grip properties od ski. The skiing distance needed to reach optimal performance depends on snow conditions. In rough, old snow will grind the ski much faster than new snow conditions. Optiwax Gripcare is recommended to be used in problematic conditions and when you need more glide
