Abstract
In a first overmolding operation, a starting element in the form of a high-cut sock lining of flexible material such as leather is coated with a composition which permits bonding and is then overmolded with a part forming an instep shank for the sole, a rear stiffening counter and a heel seat or heel body. In a second overmolding operation, the shoe is overmolded on both the upper and the body of the sole with an outer coating which consists of relatively flexible plastic material. Potential applications of the shoe include sports such as ice skating, skiing, mountaineering and fooball.
Claims5
A method of manufacture of shoes by overmolding of a layer of plastic material on a starting element, wherein said method consists in making use of a starting element in the form of a high-cut sock lining of flexible material such as leather, for example, and in a first overmolding operation in employing a rigid plastic material, in coating the starting element with a composition which permits bonding of the corresponding material and then in overmolding on said starting element a part which forms both an instep shank for the sole, a rear stiffening counter and the heel seat or heel body, then in a second overmolding operation which entails the use of a relatively flexible plastic material and, after a second coating with a composition which permits bonding of the corresponding material, the complete assembly is overmolded with an outer coating which forms a covering for the upper and gives said upper its final shape and for the main body of the sole.
