Callnak is a footwear startup redefining how shoes are designed and manufactured through additive manufacturing. We develop 100% 3D-printed footwear by combining product engineering, computational design, and high-performance flexible materials to create functional, lightweight, and customizable structures.

Our approach eliminates traditional processes such as molds, stitching, and complex assemblies, enabling full design control, local on-demand production, and rapid product iteration. Using multi-material technologies and varying hardness ranges, we optimize support, comfort, and durability within a single functional piece.

Callnak is built with an industrial and scalable vision, collaborating with manufacturers, technology centers, and strategic partners to create a new footwear value chain driven by software, data, and distributed manufacturing.
