The second sneaker from the collaboration between Rick Owens and adidas, "adidas by Rick Owens," called the Tech Runner, was unveiled at Paris Men's Fashion Week. The Tech Runner features a minimalist, monochromatic design inspired by stealth bombers. The midsole is made of a one-piece EVA resin, and the entire outsole is made of rubber. The iconic adidas three-stripe perforations and the wavy outsole visible from the side are design highlights. The shoe is crafted from a combination of grained leather, suede, and neoprene for a comfortable fit. It will be available in four colors: black, black/bone, milk, and milk/black, and is scheduled for release around summer 2014. The price has yet to be determined.
