The height of the font used should be at least 3mm. 2GT 3293 Shoe Last Size Shoe last is the parent material of shoes. It is the molding mold of the shoe that determines the shape and style of the shoe. Shoe last size refers to a complete set of shoe last sizes that are expanded and shrunk according to the specified size difference, centered around the sample last. 3GB 20400 (leather and fur) QB/T 4108-2010 (metal accessories, fasteners) Shoe materials include shoe leather, fur, textile materials, metal accessories, etc. The 4QB/T 2673 logo includes trademark, product name, shoe size, material, place of origin, company name and contact information, San Bao regulations, executive standard label, production date, color, and product number 5GB/T 3903.5-2011.

The peeling strength of the upper or the peeling strength of the bottom wall and upper is the main indicator of the adhesion fastness between the upper and outsole. Shoes with unqualified peeling strength of the upper and sole are prone to problems such as opening and cracking during wearing. Tourism shoes with shoe sizes less than 230mm and a thickness of more than 25mm in the flexure area of the sole are not tested for folding resistance according to 7GB/T 3903.1-2008. Other tourist shoes must not have cracked upper after 40000 folds; Bottom wall, upper sole, and sole adhesive opening ≤ 5.0 mm; After folding, there should be no more than 3 cracks on the sole, and the longest crack length should be ≤ 5.0mm; The sole of the shoe shall not show any color peeling off; Shoes with air (liquid) pads should not experience deep air (liquid) or collapse after folding. 8GB/T 3903.2-2008 Wear Resistance of Outsoles.
