You know Hyperfuse. That synthetic, plasticky-lookng upper build on an increasingly greater assortment of Nike shoes. You may even own a pair of Hyperfuse based shoes. Now you can get a detailed video look at exactly how the technology is in this video. It is so detailed, it could almost be training material for factories.
Whoever thought that sneakers are all about stitching is proven wrong here. The upper remains fairly stitch free thanks to other bonding techniques like high-frequency welding, ultra sonic waves and of course fuse.
Nike’s (Hyper)fuse is a new way of constructing shoe uppers through heat pressing (in this case at a temperature of 150°C and pressure of 80 kg for 30 seconds) three or more synthetic layers. This allows for strategic breathabilty, stability and durability.
However, this video also shows that fuse material alone does not make up the whole upper. To prevent skin irritation or chafing, additional lining and padding is added. At the forefoot the shoe has a half-mesh sleeve that is integrated into the tongue.
The illustrated shoe model in the clip shows off the Nike Lunar Sweet Victory training shoe, but the manufacturing process and assembly are an applicable broad look behind one of the Swoosh’s biggest technical pushes over the last few years.
