The New All-Weather Nike LunarEpic Flyknit Shield

When the Nike product team began developing the Nike LunarEpic Flyknit over two years ago, the goal was to create a running shoe with a virtually vanishing fit, fluid feel and superior softness that adapts to the body in motion. 

The new Nike LunarEpic Flyknit Shield offers the same benefits with added all-weather construction, ensuring that athletes can run with confidence and ease through the inclement conditions of the changing seasons. The shoe’s one-piece Flyknit upper is now constructed with DWR (durable, water-repellent)-coated TPU yarn and a water-repellent internal bootie to keep the foot warm and dry. The laser-siped outsole pattern—inspired by car tires—is now grooved to increase surface area, repel water and further maximize traction. The shoe’s mid-height collar continues to provide a locked-down, dynamic fit, emphasizing natural movement from the ankle to the foot.

Nike designers researched and tested multiple geometric outsole patterns on runners during deep winter on the snow and mud-filled trails of the Rocky Mountains in Colorado. In early spring, these outsoles were additionally tested in snowmelt conditions, where runners necessitate increased traction and water resistance. Eventually they found a solution that grips various surfaces while channeling water from underneath the shoe with every stride. The resulting pattern is precision-lasered into the IU foam sole, preserving heel-to-toe transitions and propelling energy return.

The Nike LunarEpic Flyknit Shield is available November 3 at and retail locations.

Commitment to Sustainability

Flyknit technology engineers every stitch of a shoe upper to deliver maximum performance while producing 60% less waste than traditional cut-and-sew methods. Since 2012, the technology has reduced nearly three and a half million pounds of waste. 

Approximately 71% of Nike footwear and apparel products contain recycled materials, in everything from apparel trims to soccer kits to Flyknit yarns. For example, since 2010, Nike has transformed more than three billion plastic bottles into recycled polyester for use in Nike performance products.
