Shoes, shoes hook heart and slit

Leather shoes, shoes, is to prevent the extension of deformation, Jiaomian touch and improve the use of reinforcement materials, shoes, materials requested a delicate touch, good ventilation, moisture, Paishi, can not color. In the high-grade leather shoes are used in the shoes of natural leather and cotton production, shoes, leather is a man-made version of the low-grade products. Below are the shoes, Tang Di, the shoes will check into a 90 ° angle, we can not crack, some fake and shoddy shoes with leather Tangdi failure of renewable non-woven Tangdi and cardboard, latex content of the material because of the low, soft after the Xihan , The soles of the hook heart - and, at the end of the starting role as a bridge between the end of a steel plate, it could Chuanchutangdi, stabbed feet.

Hook heart of the length, width, modulus, after deformation by external forces, national standards are, to a certain extent of flexibility and steel. 65 manganese steel materials to use, elastic limit load of not less than 290 N.

Check uppers suture and uppers and soles glue joints, to see whether there is a disconnection, suture the norms and tidy. The glue shoes, for its part should end with no Goukan adhesion formation, and no virtual slit open plastic phenomenon. Stickies shoes peel strength men's 54 N / cm, women's, 40 ~ 49 N / cm, the pilot on board the beginning of a sample of a plastic (that is, outside help, at the end of the glue joint deformation, discoloration phenomenon) is the failure. Consumers can, Bai, or to the press uppers, such as uppers, and at the end of the glue or a change in a plastic, adhesive that bad.
