A traction device for a boot has a felt platform with a toe section and a heel section, and a heel extension attached to the heel section. Cording passes through two pairs of passages in the toe section and in the heel extension, passing from a toe section passage to a heel extension passage to form a side stringer on each side; the cords extending forward from the heel extension pass through loops on the side stringers and are then cinched to tighten the cording against the boot. To better wrap the device about the boot, the toe section passages can be positioned on ear extensions that protrude from a body of the felt platform. Wing extensions protruding from the heel extension can be provided, with heel extension passages through which the cording passes to aid in wrapping the heel extension about the boot.
