PRIMUS LITE 3.5 Mens Obsidian Training Shoe

The Primus Lite 3.5 in Obsidian is a lightweight training shoe built for natural movement and everyday performance. Its updated upper brings the design closer to circularity, while the breathable mesh keeps the fit comfortable during runs and varied training sessions. The Primus outsole sits low to the ground for a more connected feel, making it a strong choice for experienced barefoot cross-trainers and anyone exploring barefoot performance for the first time. Inside, the Active Ortholite Performance Insole uses 98% recycled PU foam to help reduce waste and reliance on virgin plastics. At 268g based on a women’s EU 38, it stays light on foot without losing its training-ready feel.
