Bonding sole to insole upper of footwear, without additional bonds

摘要

Bonding the sole to the insole upper of footwear, comprises forming at least one recess (5) in the sole area of the insole upper (1, 4). A plastics material is poured into the recess (5), to harden and anchor the sole (2) to the insole upper (1, 4). The plastics can flow into the recess while the sole is injection moulded. Preferably the sole (2) is polyurethane, thermoplastic polyurethane, "Pebax" (RTM) or polyvinyl chloride.
