Abstract: A footwear liner includes two sides connected at a front seam and a back seam by stitching, an inner bottom piece connected to the two sides along a bottom seam by stitching, and an outer bottom piece adhered to the inner bottom piece. Each side includes an outer layer, an inner layer, and an intermediate layer that is impermeable to water and permeable to vapor. The outer bottom piece includes an outer layer and an inner layer that is impermeable to water and permeable to vapor. The two sides and the inner bottom piece cooperate to form a partial enclosure with a toe portion, a heel portion, and an open top portion. In the preferred embodiment, the front and back seams are covered by a sealing tape to waterproof the seams, and the outer bottom piece overlaps and is adhered to portions of the sides adjacent the bottom seam to form a waterproof seal between the outer bottom piece and the sides.

Abstract: A footwear sole is provided that comprises a first layer and a display element integral with the first layer. The first layer has a lower surface and an upper surface and is at least semi-transparent such that the display element is observable through the first layer.

Abstract: A pack boot includes an outsole and a pair of traction devices located on opposite ends of the outsole. The traction devices are substantially the same except oriented in opposite directions. Each traction device includes a generally planar base at a lower side of the outsole and secured to the outsole, a substantially planar anchor plate at an upper side of the outsole, a plurality of rivets extending from the base to the anchor plate and clamping the base to the anchor plate with the outsole therebetween, and a carrier having a pair of crampons and pivotally secured to the base between an active position wherein the crampons are downwardly facing and an inactive position wherein the crampons are upwardly facing. The carrier pivots about a horizontal, transverse pivot axis located at one end so that the carrier “turns over” as it pivots about 180 degrees between the active and inactive positions. The carrier has a generally planar main portion and the crampons are generally perpendicular thereto.
