A ski boot spreader has a substantially triangular block and a handle coupled to the block. The block has first and second side surfaces angled relative to each other and forming a leading nose area, a rear side surface extending from the first to the second side surface, top and bottom surfaces, and a flange extending beyond the first and second side surfaces and around the nose area and located toward the bottom surface. In one embodiment, the first and second side surfaces define first and second undercuts extending from a location at or behind the nose area to the rear side surface. In one embodiment, the bottom surface defines a third undercut extending from a location at or behind the nose area to the rear side surface.
