Dry ski slope produced in a darker green (such as in Kendal Ski Club in Cumbria, England) to comply with planning requirements. There is no indication from NorCal Extreme Sports that AstroRide has been commercially tested to any great extent. The latest arrival is from UK company Proslope who produce a matting with variable filament lengths to emulate the gradual edge grip and release of snow. As with some other surfaces, the system is coloured white, is modular, and works both with and without a misting system. Dry slope users often improve the performance of their equipment by using the hardest grade of
Ski wax snow. Glide wax is selected to minimize sliding friction for both alpine and cross-country skiing. Grip wax (also called "kick wax") provides on-snow traction for cross-country skiers, as they stride forward using classic technique. Modern plastic materials (e.g. high-modulus polyethylene and Teflon), used on ski bases, have excellent gliding properties on snow, which in many circumstances diminish the added value of a glide wax. Likewise, uni-directional textures (e.g. fish scale or micro-scale hairs) underfoot on cross-country skis can offer a practical substitute for grip wax for those skiers, using the classic technique.
