groundies | the trinity 3d-printed sneaker

Groundies.

Groundies is taking its foundational belief that footwear must match the foot’s natural anatomy and scaling it straight into a new era. Partnering with additive manufacturing disruptor Zellerfeld, the German barefoot label has dropped a fully 3D-printed capsule collection built around a highly specific concept: ‘Designed around you.’

Originally founded in Germany’s Black Forest region in 2019, Groundies has established its global identity around combining anatomical, minimalist movement with contemporary urban style. The label is most widely celebrated for pioneering TrueSense® Footwear, an internationally recognised category that integrates ultra-thin, highly flexible soles and a zero-drop foundation with mainstream street aesthetics.

The headline model of this release is the Trinity, a seamless slip-on sneaker printed from scratch as a single monolithic block with zero stitching or glue. The silhouette highlights a signature wide anatomical toe box and a highly flexible framework engineered to encourage uninhibited movement instead of compressing the digits. The design team purposefully treats the technology as an invisible helper instead of an obvious gimmick, letting the sleek form speak for itself.

The Trinity debuts in an eclectic spectrum of stone, oat, yellow, black and lilac, offering a softly sculpted look that mirrors advanced industrial architecture. Because every pair is printed exclusively on demand through Zellerfeld’s digital infrastructure, manufacturing only triggers after a customer clicks buy, completely wiping out excess pre-built warehouse inventory – another win for sustainability.

While Zellerfeld also previously made waves printing boundary-pushing projects for streetwear mainstays, this link-up with Groundies pivots the conversation entirely towards everyday physical health and long-term ergonomics. The material composition dictates the shoe’s unforced comfort, using a recyclable, TPU-based ZellerFOAM® to yield a soft, sock-like feel. The custom textile is inherently breathable, odour-resistant and entirely machine washable, flexing effortlessly with the biomechanics of the stride.

Groundies describes the capsule as a new way of thinking about footwear – one where technology becomes an invisible enabler instead of the main attraction.
