Built for those who push past the wet weather to achieve their goals, the Nike Air Zoom Pegasus 38 Shield are designed for optimal traction, complete dryness, and high performance. The upper material is comprised of a strong knit material which acts to keep your feet warm through the coldest and wettest of conditions. Skins around the toes ensure no water enters the shoes whilst providing extra warmth. The back of the tongue is insulated to keep the top of your foot dry, and the top of the trainer is coated with a PFC-free treatment for bullet-proof dryness. Under the trainer, you'll find Nike's patented Storm-Tread outsole to provide traction in wet weather, inspired by winter tyres with grooves throughout the sole for grip.
