The liner fs 02 is engineered for performance and comfort. Featuring GridSkin™, a lightweight structural mesh laminated to the exterior, it delivers durability, abrasion resistance, and flexibility without sacrificing comfort or style. PillowFoam™ adds a plush 3 mm self-molding PU layer that gently conforms to the foot for a welcoming step-in, optimized fit, and all-day comfort. A new adjustable triple-layer tongue enhances tibia support, while the checkered-print outsole absorbs vibrations to reduce fatigue and ensures durable grip for après or walking.

The liner fs 02 is also built with sustainability in mind: its foam is recycled, fabrics contain a minimum of 30% recycled content, and the rubber outsole is made with 50% bio-based materials.
