Keep your toes toasty and your feet bone dry in the workhorse with wings that does all the dirty work to shield your runs from bad weather. This design can help you look forward to the misty drizzle, the angry, dark clouds, those shivery morning outings that bite and bark. The Nike Air Zoom Pegasus 39 Shield provides water protection and all-terrain tire-like traction for downpours, first, but with a cozy fleece feel on the inside, thanks to an unbeatable duo of heathered lining and structured insulation inspired by Nike's Aeroloft technology that ensures your feet will feel like it's a summery July day in the dead of winter.
