Started from 1937, achievement many astonishing facts, but this enabled to become the world first shoe sole! Every year produces pair of shoe soles Each season has kind of shoe sole birth to sell the global 120 countries with to surpass footwear brand cooperation all designs to undergo the severe test on the spot to Vibram experience to complete over a thousand great movements the achievement material quality uses very many different rubber compound, each kind of compound is mixes carefully according to each model of shoe sole different use and the demand, therefore each model of shoe sole can present the different physical property, for example: Vibram Five Fingers shoes Elasticity, density, degree of hardness, skid prevention, resistance to wear…And so on. Each compound is defers to the different product the demand (for example: Leisure, comfortable, movement), and guaranteed that has the best function performance. uses rubber including natural rubber and synthetic rubber, because vibram SPRINT they have the different characteristic, the natural rubber is gathers from the rubber tree comes, has the very good elasticity. But the synthetic rubber mainly comes from the petroleum, compared with is wear-resisting and is durable. according to the different product’s demand the natural rubber and the synthetic rubber mix, enables vibram running shoes the shoe sole which produces to be possible to have the most correct quality and the performance. Actually because the shoe sole will act according to the different use to have the different shoes grain design, for example: The mountaineering use’s shoe sole, shoe sole’s pellet is quite usually big, the tooth vibram shoes grain is also quite deep, but healthy good shoes’ tooth grain on relative shallow, if is the general urban leisure shoe sole, the tooth grain is very possible is very simple across to the grain. But the friction force and the skid prevention is shoe sole’s Vibram Men Shoes body both sides actually, looked whether your shoe sole does use in the correct road surface. For example: In mountaineering time, because contacts the ground is mostly the crushed stone, the earth, the lawn, but these road surfaces can cause the tooth grain which the mountain boots break out to penetrate into the soft road Vibram Fivefingers Classic Shoes surface, lets the tooth grain’s vertical part which breaks out become with the ground contact part, like this also increased the shoe sole and the ground contacted area, then increased the friction force, but if your mountain boots put on to the general ground in even are the ceramic tile road surface…And so on smooth road surface, because the mountain boots break out the tooth grain is Vibram Fivefingers Speed Shoes unable to penetrate into the road surface, therefore the shoes and the ground contacted area becomes very small (, because only then tooth grain breaks out part underneath), therefore the friction force on remarkable reduced, will certainly also feel unusual sliding, in this kind of situation, if you will be put on shoes the grain even shoe sole to try, believed that the skid prevention will be friends with the mountain boots are more.
