Described are methods for manufacturing a plastic component, in particular a cushioning element for sports apparel, a plastic component manufactured with such methods, for example a sole or a part of a sole for a shoe, and a shoe with such a sole. The method for the manufacture of a plastic component includes loading a mold with a first material includes particles of an expanded material and fusing the surfaces of the particles by supplying energy. The energy is supplied in the form of at least one electromagnetic field.

A shoe insole includes a semi-rigid shell for providing a wearer with extended comfort. The semi-rigid shell includes a notch which is located on the outward side of the wearer's foot and accommodates pronation of the foot during use. Additionally, the semi-rigid shell includes an extended side portion which is located opposite of the notch side on an inner side of the wearer's foot. The semi-rigid shell is shorter in length than the length of a shoe sole and slightly shorter in width and may be combined with an insole comfort cover to provide cushion between the wearer's foot and the semi-rigid shell.

A sole includes: a midsole main body; an elastic portion; and a pressing member. The midsole main body includes a containing portion. The elastic portion is contained in the containing portion in a compressed state. The pressing member has an elastic modulus higher than an elastic modulus of the elastic portion in the compressed state, and presses the elastic portion so that the elastic portion is maintained in the compressed state. The elastic modulus of the elastic portion in the compressed state is larger than an elastic modulus of the midsole main body.

The present invention is related to a shoe, the shoe including: a first outsole comprising a bottom portion which contacts the ground, and a plurality of first protruding portions each of which has a dome shape and protrudes upward from the bottom portion, and a second outsole comprising a support portion disposed on the bottom portion, and a plurality of second protruding portions each of which has a dome shape and protrudes downward from the support portion. Protruding end portions of the plurality of second protruding portions are bonded to protruding end portions of the plurality of first protruding portions, respectively.

The present disclosure provides footwear with an internal metatarsal guard and a related manufacturing method. In the depicted embodiment, the metatarsal guard is internal in that it is located under the outer layer of the footwear. In the depicted embodiment, the existence of the metatarsal guard can be visually detected from the outside of the footwear being that the metatarsal guard is located in a raised area in vamp of the footwear. The footwear is constructed such that the metatarsal guard does not impinge into the foot volume of the footwear, and the metatarsal protection also is arranged and configured to maintain a high degree of flexibility in the footwear.

Disclosed are a shock absorption and ventilation enhanced shoe sole and a preparation method therefor. The shoe sole comprises a body. At least one layer of communication-type air passage is provided in the body, and a plurality of first air holes provided in the circumferential side face of the body and a plurality of second air holes provided in the upper surface of the body cooperate, so that air intake and deflation for heat exhaust can be alternately achieved in the process of alternately lifting a foot and treading of a user, thereby preventing heat from accumulating on the foot sole, being beneficial to foot health, reducing foot perspiration, and helping slow down heart rate acceleration; and in addition, the shoe sole can achieve the functions of shock absorption, buffering, ventilation and power assistance, so that the shoe sole is more comfortable to wear.
