Nike Spark Lightweight No-Show Running Socks LIGHTWEIGHT SUPPORT WITH BAREFOOT FEELING The Nike Spark Lightweight Socks feature a thin design with sweat-wicking technology and mesh fabric to keep you dry and cool. Additional yarn in the footbed and at the ankles provides subtle cushioning and gives you soft support with every step. The reflective elements are located in key areas and ensure that these socks stand out from previous versions. Reflective elements for your runs We've updated our Spark Lightweight socks with reflective details on the collar. Reflective yarns are also integrated into the mesh pattern on the back of the foot. Lightweight feel The lightweight material provides a barefoot-like feel. More yarn in the footbed and ankle area provides some cushioning in key areas. Breathability on the back of the foot Mesh on the back of the foot keeps your feet pleasantly cool. The striped pattern on the foot shows where the mesh has been placed. Sweat-wicking technology draws perspiration away from the skin so it evaporates faster, keeping you dry and comfortable. The arch band follows the shape of the foot for a secure fit and feel.
