Nike's LunarEpic Flyknit runner just got better with the introduction of the Shield version of the shoe, which aims to make it appropriate in all sorts of inclement weather. Upgrades include a new type of yarn on the upper and a water-repellant bootie on the inside.
This time around the Flyknit design uses a durable, water-repellant TPU yarn, the benefits of which are shown off in the images gathered here. The outsole is also upgraded with a tire-like tread tested in Colorado's Rocky Mountains.
The Nike LunarEpic Flyknit Shield will release on Nov. 3.
