Shoe for use with a cross-country ski

A ski shoe for use with a cross-country ski having a three-armed web projecting from the ski surface and one arm extending in the longitudinal direction of the ski and two arms diverging therefrom, comprising sole means of synthetic resin, the sole means including a heel portion defining a recess of V-shaped cross section, the recess comprising a rectilinear center recess portion extending in said direction for engaging the one web arm and thereby holding the heel portion on the ski against lateral displacement as well as two diverging rectilinear recess portions extending from an end of the center recess portion for engaging the two diverging web arms, the diverging recess portions enclosing an angle between 90.degree. and 270.degree., beveled transition zones extending between the underside of the sole and the V-shaped recess, and upwardly projecting lateral edges arranged only forward of the heel portion.

A ski shoe for use with a cross-country ski having a web project from the ski surface and extending in the longitudinal direction of the ski, comprising sole means of synthetic resin extending in an upwardly curvilinear plane, the sole means including a heel portion defining a recess of V-shaped cross section extending in said direction for engaging the web and thereby holding the heel portion on the ski against lateral displacement, and upwardly projecting lateral edges arranged forwardly of the heel portion.

A ski shoe for use with a cross-country ski having a web projecting from the ski surface and extending in the longitudinal direction of the ski, comprising a sole means of synthetic resin comprising an outer sole and an inner sole of a rigid but thin sheet material bonded to the outer sole in transverse strips, the sole means including a heel portion defining a recess of V-shaped cross section extending in said direction for engaging the web and thereby holding the heel portion on the ski against lateral displacement, and upwardly projecting lateral edges forwardly of the heel portion.

A ski shoe for use with a cross-country ski, comprisng an integral sole means of synthetic resin, the sole means including an inner sole insert constituted by thin strips of rigid material extending transversely to the sole means and imparting stiffness to the sole means in a transverse direction, the sole means having lateral edges and a portion extending therebetween and adapted to be in registry with an underlying ski having lateral edges extending in the direction of the lateral edges of the sole means, the sole means portion being defined between two lines overlying the lateral ski edges, the strips tapering inwardly from said lines towards the lateral edges of the sole means, on the one hand, and towards the center of the sole means portion, on the other hand, and the strips having a maximum width along said lines.

A ski shoe for use with a cross-country ski having a binding web with a plurality of arms extending at an angle to each other, comprising an integral sole means of synthetic resin, the sole means including a heel portion defining a recess with a like plurality of arms, the arms of the binding web and of the recess having complementary V-shaped cross sections for engagement with each other, and the sole means further including an inner sole insert imparting stiffness to the sole means in a transverse direction.
