The ultra-streamlined SeeYa is our newest performance option for serious minimalist runners. Designed to bring you even closer to the barefoot sensation, Vibram FiveFingers radically reduced overall weight and material with a more breathable mesh upper to deliver true, performance-driven footwear. Minimum rubber thickness in the outsole maximizes "foot feel" and flexibility, while a soft TPU midsole further reduces thickness and weight for natural movement. A stitched-in polyurethane insole protects skin and foot tissue during longer runs. For a snug fit, the lightweight, single-layer, stretch mesh upper has an adjustable hook-and-loop closure. 3M reflective applications for night running.
