Mould and method for producing footwear

A mould for producing a shoe by direct injection molding a sole onto an upper, wherein the sole comprises, a tread and a midsole, wherein the midsole is composed of a first layer and a second layer;

• the mould comprising a base, a pair of first half-rings, a lid, a pair of second half-rings and a mould last, wherein the first half-rings are designed to be arranged close together such that they abut against the base and against the lid, so as to define a first mould cavity for moulding the first layer of the midsole, and wherein, while the first half-rings are abutting against the base, the second half-rings are designed to be arranged close together, such that they lie over the first half-rings and abut against the upper, fitted onto the mould last, so as to define a second mould cavity for moulding the second layer of the midsole;
• the mould being characterized in that the first half-rings are provided with guiding means, designed to slidably engage with corresponding guiding means provided in the base, so as to allow the first half-rings to be moved away from and towards each other, the first half-rings being hinged at the bottom with said guiding means so as to be able to rotate about an axis of rotation.
