RARE: These are gorgeous! Sports Illustrated did an article about them. They are European size 41, which translates to a size 10 or 10.5.In the early 2000's, Antje Elle, a German who graduated from the Munich School for Fashion Graphic Design, and Baldovino Mattiazzo, a designer who studied fashion in Florence, fell in love with each other and the game of golf.One offspring of their partnership is Duca del Cosma, a golf shoe and apparel brand in which Italian flamboyance meets German precision. According to the current owner, Frank van Wezel, "Our collections are inspired by the Italian way of living and produced with great attention to detail."Duca del Cosma golf shoes are produced with leather from the best tanneries in Europe, Goodyear welted construction, merino wool soft linings, outsoles from durable rubber compounds, first class real cotton shoe laces and trendy colors.Unaffected by the initial resistance, Mattiazzo has not shied away from eccentric patterns and wild colors. The color red, reminiscent of Italian emblems such as Ferrari, Alfa Romeo, Valentino, and Vespa, is the signature color of Duca del Cosma's designer golf and lifestyle shoes and apparel.
