Abstract

A footwear has a novel shoe upper. The shoe upper is soft and wear-resisting. The making of the shoe upper is simple and the cost is low.

Claims

1. A footwear having a novel shoe upper, comprising:

a shoe sole; and

a shoe upper deposed on said shoe sole,

wherein said shoe upper comprises

(a) a base layer;

(b) a blowing layer deposed on said base layer;

(c) a shoe-upper layer deposed on said blowing layer; and

(d) a cover layer deposed on said shoe-upper layer;

wherein said blowing layer is made of a material obtained by mixing

(a) a 80 weight percents (wt %) of a first Polyolefin Elastomer (POE);

(b) a 20 wt % of a first Styrene-Ethylene/Butylene-Styrene (SEBS) block copolymer;

(c) a 3 parts per hundred of rubber (PHR) of a blowing agent;

(d) a 10 PHR of a first filler;

(e) a 0.4 PHR of a first slip agent; and

(f) a 0.4 PHR of a blowing additive; and

wherein said shoe-up per layer is made of a material obtained by mixing

(a) a 20 wt % of a Hydrogenated Styrene-butadiene rubber (H-SBR);

(b) a 35 wt % of a second SEBS block copolymer;

(c) a 15 wt % of a second POE;

(d) a 30 wt % of a Styrene-Butadiene-Styrene (SBS);

(e) a 5 PHR of a second filler;

(f) a 0.3 PHR of an anti-oxidant agent;

(g) a 0.3 PHR of an anti-ultraviolet (anti-UV) agent; and

(h) a 0.5 PHR of a second slip agent.

2. The footwear according to claim 1,

wherein said base layer is a fabric.

3. The footwear according to claim 1,
