Problems solved by technology

While this solution can work well in some sports like tennis, cushioning is not the best way to reduce the risk of injury during running because the cushioning absorbs too much energy from the runner

Embodiment Construction

[0035] Figure 1aIt is a perspective view of bottom 7. In a preferred embodiment, the sole consists of three layers, namely a midsole 1 as a first layer, a second intermediate layer 2 and a third layer 3 forming an outsole. The arch pad 4 is placed above the midsole. Figure 1b showing along Figure 1a The bottom of the longitudinal sectional view of the axis A-A. For clarity, the medial foot support structure has been placed in Figure 1a is omitted in the view, but in Figure 11 It can be seen in the reference numeral 158 that it is indicated.

[0036] In a preferred embodiment, the midsole 1 is made of light polyurethane (PU) material, also known as lightweight PU. The material is a known special variant of PU with a low density (0.35 g / cm 3 ), which is a lightweight material. A further feature is the ability to return energy absorbed from the runner well, which is important for long distance running. Shore A (Shore A) hardness between 38 and 40. Alternatively, ethyl...

Abstract

A midsole for a shoe, in particular a running shoe, is described which midsole is asymmetric in a midfoot area, has an upper heel portion embracing the calcaneus of a wearer and has an upwardly extending toe end. In the midfoot area a vertical medial support structure originates from the midsole and supportively embraces the arch. Correspondingly, a vertical lateral support structure supports the lateral side of the foot in the midfoot area. The medial support structure covers a larger area than the lateral support structure, and is connected to the vertically extending upper heel portion of the midsole. The toe end of the midsole is extended upwardly, and provides in combination with the vertically extending upper heel portion and said vertically extending medial and lateral arch support structures a midsole which firmly embraces the foot. The result is a shoe, in particular a running shoe, which reduces the risk of injury during running.

Description

technical field [0001] This invention relates to midsoles with arch support, and more particularly to midsoles for running shoes. Background technique [0002] A prior art running shoe shares the concept of foot protection. More precisely, such shoes were considered a protector for the feet. This protection concept has resulted in relatively heavy running shoes, which usually have a highly cushioned sole or insole to moderate the reaction forces from the heel strike and on the ankle joint and leg. Another type of running shoe is an ultra-light shoe, usually under 300 grams. This type is a minimalist type (minimalist) with a thin sole and a thin upper. When designing shoes, the footwear industry has long considered the naturally moving foot to be the ideal state of motion, for example, barefoot running on grass, where the foot, unrestricted by the shoe, is allowed to perform its natural movements. However, once the shoe is on the foot, the natural movement of the foot is ...
