Athletic Propulsion Labs - Athletic Propulsion Labs’ latest innovation – the TechLoom Bliss trainers – are crafted to a streamlined slip-on silhouette from high-stretch mesh, and this black and white pair capture a futuristic aesthetic. They’re designed to be lightweight – ideal for running – and are secured with a black elasticated satin strap across the forefoot, then enhanced with foam PropeliumTM cushioning in the midsole with a traction-led outsole sitting underfoot. Runs true to size.
