Abstract: A protective gaiter which extends from a wearer's instep to just below his knee. A portion of the gaiter forms a completely closed pocket which contains an energy-absorbing pad. The pocket and the pad are both elongated, covering substantially the length of the gaiter, and include a concavely shaped bottom edge which lets the gaiter be conveniently positioned around the wearer's instep so that it fits over and protects the wearer's shinbones, as well as covering many of the major bones and muscles of the wearer's leg.In the manufacture of the protective gaiter, identical front and liner panels and a somewhat smaller, interposed back panel are aligned and sewn together along one longitudnal edge. An elastic strip, which forms the stirrup of the protective gaiter, is next secured between opposing ends of the bottom edges of the front and liner panels, which bottom edges are then sewn together. The other longitudinal edges of the front, liner and back panels are then aligned and sewn together.

Abstract: A shoe construction including an upper member preferably divided into two pieces, an upper and a mudguard piece in which the mudguard piece has a pair of depending side portions extending beneath the upper and joined along longitudinal abutting edges between the heel portion and the forepart of the upper member.The method of making this shoe includes slip-lasting the upper member after the upper and the mudguard piece have been secured together, and after the bottom edges of the mudguard piece have been secured. Thus, lasting is facilitated, because only the forepart and heel portions of the upper member need be lasted. Moreover, less attention is required for fitting the upper member about the last since the shape and fit has been substantially determined by pre-securing the bottom edges of the depending mudguard side portions.
