The invention disclosed herein provides a replaceable edge cassette for skis or a snowboard. The skis have a top, a base, a core, two sides, and edges along the sides of the base. The cassette includes an edge portion removably secured adjacent the base of the ski. The edge portion has an attachment portion for securing the edge portion to the ski and a peripheral portion for contact with the surface to be ridden. The cassette includes a sidewall portion secured to the edge portion. A fastener is connectable through the sidewall portion to be secured to the ski adjacent the core. Base material is also secured beneath the removable edge portion so as to be adjacent the main base portion when the cassette is secured to the side of the ski. The edge cassette is removable and replaceable by removing the fasteners secured through the sidewall. The edge alone may also be separately replaceable by removing it from the sidewall portion.
