The person in question, for On, is named Johannes: a college student fascinated by Spider Man who began experimenting with hot glue to try to recreate the effect that spider web effect that easily and instantly builds a structure around an object. For example, the shape of a shoe.
His school project is noticed by On's Innovation team during a trade show in Milan, and a long development process begins, starting with an intuition and resulting in a patent that totally changes the approach to the construction of sports shoes: the LightSpray.
The idea is as simple as it is ingenious: it involves spraying a 1.5-kilometer filament following a complicated weave pattern that allows the complete upper to be created in a single pass directly over the midsole, avoiding glue and stitching and reducing emissions by 75 percent compared to the classic processing of a sports shoe. All, in just three minutes.
The effect for the wearer is that of a second skin. The shoe was tested on numerous athletes both in the design phase and in its final version, namely the Cloudboom Strike LS, which weighs only 170 grams, including 30 grams of upper.
