发明名称 Sports shoes made of plastic
摘要 The specification describes a sports shoe particularly a ski boot which holds the foot free of pain in a fixed manner. The shoe has a good heel fit owing to the use of an instep strap which fixes the foot laterally and the lower leg partly at its front. At the closing border of the upper the shoe is snow-tight and supports the lower leg owing to the provision of elastic parts in the region over the insetp of the shoe and over the heel. These parts have an elasticity which decreases towards the boot sole.
