Intermediate to advanced skis and snowboards may be somewhat wider or stiffer than beginner-intermediate skis and snowboards, usually with a stronger wood core and sandwich sidewall construction. Intermediate to advanced boots and bindings range from softer flexing freestyle options to stiffer choices built for stability at speed.
