Nike Zoom Skylon 11 Shoes The Skylon 11 is back with a bang. This aerodynamic tech runner made its debut in the late 2000s and quickly made a (highly cushioned) impact. A chunky Air Zoom midsole features deep grooves and exposed pods for a balanced combo of cushion and flexibility. Zoom Air in the heel and Cushlon midsole serve responsive cushioning. Nike Free-inspired flex grooves offer a responsive, natural feel. Mesh upper is paired with synthetic leather overlays to blend breathability with durability and support.
