Leather soles to leather-based, higher prices. Its advantages are easy to shape, the same type, fit, good elasticity, can reduce the impact and not fatigue, ventilation, absorption of moisture, etc., while easy processing, type easy to show beauty. Hard texture is not easy to be pierced, but by water, oil soaked after easy to warp deformation or rot. Its main features 1) have a good thermal insulation to ensure that the feet in the shoe within the appropriate temperature 2) light weight, weight per square centimeter in the 0.95 ~ 1.05 grams, just the same as the water density. Can be waterproof and in the shoes no longer wet when the release of moisture adidas superstar to ensure that shoes in a comfortable state. 3) Unique three-dimensional fiber structure, the soles are not broken when bent at 180 degrees. Can be effectively adapt to the foot shape, can effectively support the impact of the ground than the same thickness of other materials soles more effective protection 2, rubber bottom (RB): RB is the English rubber (rubber) abbreviation; hot plastic molding, sub-natural rubber With recycled rubber. Weight, oil resistance, molding at the end must be rough in the face, the temperature is easy to shorten, the color is inconsistent Advantages: good wear resistance, non-slip, flexible, easy to break, softness is better, good extension , Shrinkage adidas women stability, good hardness, adidas sneakers good bending, waterproof. But not hard, easy to be penetrated; breathability, hygroscopicity is not good, afraid of oil soaking, not in the car gas station and other contact with the oil (the quality of the problem), not easy to corrosion (environmental issues) Place to wear.
