3D printed by

We reimagined the slip-on from the ground up with the APTHCRY MULE, created in collaboration with Zellerfeld through their proprietary 3D printing process that replaces traditional assembly with pure digital fabrication. Each pair is printed in zellerFOAM, a recyclable TPU built for comfort, breathability, and structure. The seamless one-piece form flows with sculpted lines, vented panels, and a lattice sole that rides soft and responsive underfoot. This isn’t just footwear, it’s an artifact of design and tech colliding, pushing sneaker culture into the future with every step.
