Abstract
A shoe including an upper material using a double raschel warp knitted fabric is provided. The upper material includes a first surface having a non-mesh structure and a second surface having a non-mesh structure part (A) and mesh structure parts (B, C). The burst strengths burst strengths A, B and C of the parts (A, B and C) satisfy the relationship: A>B>C. The non-mesh structure part (A) is disposed in a part surrounding the tiptoe, a part connecting to a shoe sole and disposed in both sides of the foot for example, in a stripe. The mesh structure part (B) is disposed in the vicinity of the surface of the toe and the mesh structure part (C) is disposed in the both sides of the foot for example, in a stripe. Thus, a shoe having lightweight, air permeability and durability and a double raschel knitted fabric used for the shoe are provided.
