Year Introduced: 2010

Back in the early days, there weren't many choices when it came to upper materials: There was canvas, there was leather, there was suede, there was nylon. That was pretty much it. Lightweight meant nylon, durable meant leather, breathable meant either open mesh or punching holes in leather and suede. "Hyperfuse," which utilized multiple layers of thin, synthetic material, took care of both properties. Leather and suede both still have their uses, but as far as pure performance goes, fuse is hard to beat.
