Vibram S.p.A. is an Italian company based in Albizzate that both manufactures and licenses the production of Vibram-branded rubber outsoles for footwear. The company is named after its founder, Vitale Bramani.〔http://www.vibramfivefingers.com/roots/〕 Bramani is credited with inventing the first rubber lug soles for shoes. These soles were first used on mountaineering boots, replacing leather soles fitted with hobnails or steel cleats, commonly used up until then. "Lug soles" are a type of outer sole found on heavy-duty and utility shoes such as hiking boots or work boots. The soles produced by Vibram are called Vibram soles, Vibram rubber, or simply Vibram. == History == In 1935, the deaths of six of Bramani's mountaineering friends in the Italian Alps was partly blamed on inadequate footwear. The tragedy drove Bramani to develop a new climbing sole. Two years later, he patented his invention and launched the first rubber lug soles on the market with a tread design called the "Carrarmato" (~ "tank tread"), with the financial backing of Leopoldo Pirelli of Pirelli tires. The sole was designed to provide excellent traction on the widest range of surfaces, have a high degree of abrasion resistance and was made using the latest vulcanized rubber of the time. In 1954, the first successful ascent to the summit of K2 was made by an Italian expedition wearing Vibram rubber on their soles. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vibram」の詳細全文を読む スポンサード リンク
