A braking member attachable to a sledder's boot is provided. The braking member includes a braking surface that is oriented at a specific ranges of angles with respect to the boot. In use, the braking surface engages the snow like an anchor as the sledder traverses snow covered terrain, thereby producing a braking force against sled forward movement. In one embodiment, the braking member is rotatably attached to the boot and is moveable between a first, walking position, and a second, braking position. In another embodiment, the braking member is fixed in the braking position.
