The form language of the Foam Runners were polarizing upon first leaks, with many making fun of the alien-like shape designed by Steven Smith.
But the forms all serve a functional purpose. The thickness of the vamp prevents heavy creasing at the flex point, while the hole patterns create areas where the shoe can bend and breathe. The uniqueness of the form is very similar to the shape of the Ohmu fromNausicaä, with the eyes mimicking the holes on the vamp.
The Ohmu are giant insects that live within the Sea of Corruption, an area uninhabitable by humans. Their form is reminiscent of pillbugs and they molt periodically, leaving behind shells harder than ceramics with glass-like eyelids that can be harvested for weapons.
