Pair of shoes equipped with welt having multi-color side wall

Abstract

Provided is a pair of shoes equipped with a welt having a multi-color side wall. One shoe comprises a sole unit, a vamp unit connected with the sole unit and a welt unit arranged at the sole unit. The welt unit extends along a length direction and has a base table and the side wall arranged on the base table. The base table is provided with a top surface. The side wall is arranged on the top surface and provided with a wall top surface and an outer wall surface connected to the top surface of the wall. The maximum height of the side wall is defined by a height direction in real terms between the top surface of the wall and the top surface. The maximum height of the side wall is no less than 1.5mm. Multiple color regions which are stacked in the height direction in real terms and respectively extend along the length direction are defined by the outer wall surface so that the visual effect displaying dual colors or multiple colors is produced. Therefore, the variability in external appearance of the pair of shoes is improved. By reducing thickness and weight of the welt unit, the shoes can be worn in a telescopic manner. The problem that the welt unit and the vamp unit are prevented against degumming in one day is avoided.

Description

technical field [0001] The invention relates to a shoe, in particular to a shoe with a multi-color welt side wall. Background technique [0002] Such as figure 1 As shown, an existing safety shoe (approved U.S. Patent No. US 8,458,925 to the applicant of the case) comprises a sole unit 1, an upper unit 2 arranged on the sole unit 1 and having a toe head 201, and a set The welt unit 3 is on the sole unit 1 and surrounds the upper unit 2 . The strip unit 3 has a bottom strip layer 301, and a top strip layer 302 stacked on the bottom strip layer 301, the bottom strip layer 301 has a base 303, and the base 303 has a bottom surface 304, The top edge layer 302 has a base portion 305, and a flange portion 306, the base portion 305 has a top surface 307, the top surface 307 of the top edge layer 302 and the bottom surface 304 of the bottom edge layer 301 A vertical distance H is not less than 6mm, and some products in the industry have even made the vertical distance H 9-11mm.

Problems solved by technology

[0003] However, since the base 303 of the bottom strip layer 301 plus the base 305 of the top strip layer 302 are very thick (at least 6mm, generally even as thick as 9-11mm in application implementation), plus the base The width W of 303, 305 is also quite wide, therefore, this welt unit 3 can be said to be thick, heavy and wide as a whole, like this, not only can increase the manufacturing cost of this welt unit 3, and this welt unit 3 also can cause The shoe does not flex well when worn

[0004] Furthermore, because the thickness of the base portion 303, 305 of the strip unit 3 is large and wide, it often requires a relatively large force to bend the strip unit 3 during shoe manufacture. Even so, the strip unit 3 and the strip unit The vamp unit 2 is still quite prone to incomplete gluing at the corners, resulting in the problem of degumming between the welt unit 3 and the vamp unit 2 in the future

[0005] In addition, although the bottom welt layer 301 and the top welt layer 302 of the welt unit 3 can be manufactured in different colors, in order to improve the appearance of the shoe by changing the color of the base 303, 305 on the outer surface, However, in fact, in the manufacturing process of shoes, the outer surfaces of the bases 303, 305 must be ground, which will significantly affect the color effect of the outer surfaces of the bases 303, 305. The bases 303, 305 does not display the expected color on the outer side of the
