Abstract: Comprehensive wrapping and waterproof snow boots and a production process thereof are provided. Each boot comprises an upper, a shell and a sole, wherein the shell is connected with the sole, and the shell covers the surface of the upper; the upper is composed of an inner bootie and a vamp for preventing water and siphoning; and the upper is connected with the sole and the shell by a PU bridging layer. The making process is simple and can omit a sole laying procedure and an upper-shell assembly procedure; the inner bootie enables the upper and the sole to be completely attached to a last, realizes good wearing comfort and barefoot feeling, achieves maximum sports shock absorbing and assisting function and comfortably wraps the foot. By reducing EVA & RB materials and increasing PU material, the dissolution proportion of the boots is increased, and the snow boots are more environment-friendly.

Abstract: Comprehensive wrapping and environment-friendly shoes and a production process thereof are provided. Each shoe comprises an upper and a sole. The upper includes an inner bootie and a vamp; the inner bootie includes a lining and a PU inner pad which are connected; the collars of the inner bootie and the vamp are connected, and the vamp lower edge extends to the inner pad bottom surface and is connected therewith. The making process is simple and can save sole laying and insole assembly procedures and simplify the upper marking procedure; the inner bootie enables the upper and the sole to be completely attached to a last, realizes good wearing comfort and barefoot feeling, achieves maximum sports shock absorbing and assisting function and comfortably wraps the foot. By reducing EVA & RB materials and increasing PU material, the dissolution proportion of the shoes is increased, and the shoes are more environment-friendly.

Abstract: A pair of environment-friendly popcorn bridging shoes and a production process thereof are provided. The upper of each bridging shoe comprises an inner bootie, which is composed of a lining and an inner pad formed by single injection molding, and a vamp; the collar of the inner bootie is fixedly connected with that of the vamp, and the lower edge of the vamp wrapped by a PU bridging layer extends to the bottom surface of the inner pad fixedly connected with the same; the upper and a popcorn sole made of mixed PU and TPU popcorn particles are integrally connected by the PU bridging layer. The shoe making process is simpler, and firmer bonding and better shock absorbing performance of the shoes are achieved; the vamp and the sole can well wrap the foot; and the dissolution proportion of shoes is increased by increasing the consumption of the PU material.

Abstract: The present invention is generally related to an article of footwear, in particular, to an improved article of footwear that has a polyurethane bridge layer joining sole and upper, without having to use glue or some other bonding agent and a method of manufacturing such an article of footwear.
