Embodiment 2

[0117] Figure 8 ~ Figure 1 1 represents Example 2.

[0118] Such as Figure 8 As shown in the thick dots of , the reinforcement member 3 is an integral resin component to form the inner reinforcement part 34 , the outer reinforcement part 35 , the first connection reinforcement part 37 , the second connection reinforcement part 38 and the connection part 39 .

[0119] The inner reinforcement part 34 extends in the front-rear direction L from the front end of the big toe along the inner side IN of the forefoot part Ff so as to connect the three second island-like parts 42 .

[0120] The outer reinforcing portion 35 extends in the front-rear direction L from the front end of the big toe along the outer side OUT of the forefoot portion Ff so as to connect the three second island-shaped portions 42 .

[0121] In addition, the "forefoot part" in this specification refers to the part Fm ( Figure 8 ) in front of it.

[0122] Such as Figure 10 As shown, the inner and outer rei...

Abstract

A structure for a sole whose front foot portion is weight-lightened to limit excessive bending, improving running efficiency. [MEANS FOR SOLVING PROBLEMS] The shoe sole has a mid sole (2) for cushioning a landing impact, an outer sole (1) placed under the mid sole (2) and coming into contact with the ground, and a strengthening element (3) for limiting bending of the front foot portion (Ff) in kick. The strengthening element (3) forms a loop by constructing an integrated resin part by an inner strengthening section (34) extending in the front-rear direction (L) along the inner side (IN) of the front foot section, an outer strengthening section (33) extending in the front-rear direction along the outer side of the front foot section (Ff), a connection strengthening section (37) for connecting and strengthening between the inner and outer strengthening sections (33, 34), and a connection section (38) for connecting, at a position behind the connection strengthening section (37), the inner strengthening section (34) and the outer strengthening section (33).

Description

[0001] This application is a divisional application with the title of the invention "Structure of the forefoot of the sole", the international application date is September 26, 2007, the international application number is PCT / JP2007 / 068609, and the national application number is 200780038301.1 technical field [0002] The present invention relates to the structure of the forefoot portion of a shoe sole. Background technique [0003] In recent years, there have been proposed soles in which the forefoot portion of the sole has island-shaped portions separated front-rear or inside-outside, (for example, the following patent documents 1, 2). In such soles, the grooves between the islands allow the sole to bend easily. [0004] Patent Document 1: WO 2006 / 038338A1 [0005] Patent Document 2: WO 2004 / 066771A1 [0006] The following Patent Document 3 discloses a rebounding member that crosses and reinforces a groove of the sole of the forefoot. The rebound component is arranged ...
