Don't let wet weather stop your running routine. The Nike Air Zoom Pegasus 37 Shield helps deliver the support you need in cold conditions. A water-repellent design helps keep you dry on every mile. Tough traction delivers tyre-inspired grip on slick streets. Wet-Weather Traction The Storm-Tread outsole provides traction in wet weather. It features textures inspired by all-winter tyres. Micro grooves grab the road, while multi-directional shapes help shed water for direct contact with the pavement. Lightweight Coverage A 1/2-length weatherised shroud is lightweight and breathable, helping to keep your forefoot dry. Inspired by performance outerwear, the shroud has a DWR (durable, water-repellent) finish to help repel water.
