Abstract
A partly multi-layered upper, comprising a base upper with top opening, lacing means and a closed lasting margin, with fixed insole and a partly additional upper with cut-outs for lacing means, wherein the partly additional upper surrounds at least a hindfoot region of the base upper forming part of a sports shoe, should be created, increasing stability and robustness of the sports shoe. This is reached because the partly additional upper comprises a midsole margin and is suitable to be wrapped around a midsole edge of a midsole, fastened in a taut manner and glued with its midsole margin at least partly to an undersurface of the midsole in a taut manner.

A partly multi-layered upper, the partly multi-layered upper comprising:
- a base upper with top opening, lacing means and a closed lasting margin, with a fixed insole;
- and
- a partly additional upper with cut-outs for the lacing means, wherein the partly additional upper surrounds at least a hindfoot region of the base upper forming part of a sports shoe,
- wherein the partly additional upper comprises a midsole margin and is suitable to be wrapped around a midsole edge of a midsole, fastened in a taut manner and glued with its midsole margin at least partly to an undersurface of the midsole in a taut manner.
A sports shoe with a closed upper with a lasting margin and an insole inserted in the closed upper, a midsole and an outsole, wherein the upper is attached to the midsole and the outsole is attached to the midsole,
- wherein the upper is a partly multi-layered upper, comprising a closed base upper and a partly additional upper, wherein a midsole margin of the partly additional upper is partially folded over at least in the hindfoot region around the base upper and the midsole with a midsole edge, folded over to an undersurface of the midsole, wherein the partly additional upper is fastened in a taut manner and secured by bonding before an outsole is bonded to the undersurface of the midsole with folded over midsole margin.
A method of manufacturing of a sports shoe, the method comprising:
- pulling a base upper with a top opening, a bottom region, lacing means and a lasting margin over a shoe last,
- closing the base upper on the side opposite the top opening at the lasting margin with an insole using the Strobel technique,
- gluing a midsole with a midsole inner surface, below the shoe last with the surrounding base upper, closed with the insole,
- pulling a partly additional upper with cut-outs for lacing means and a midsole margin over the closed base upper on the shoe last, enclosing at least the hindfoot region,
- pulling the partly additional upper tight in a direction of the midsole, folding over underneath the midsole under tension, before being attached underneath the midsole by gluing.
