Nike Air Zoom Pegasus 39 Shield Women's Running Shoes

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, and those shivery morning outings that bite and bark.

Crafted from knit material, the upper is like a warm, dry jacket for your feet, keeping them toasty in cold and wet weather conditions. Aeroloft-inspired structured insulation technology and a heathered lining keep feet feeling toasty in adverse conditions so you can keep going even when the weather takes a turn for the worse. Skins around the toes are placed in areas where water can traditionally seep in to prevent water ingress, helping to keep you dry. The back of the tongue is also insulated, so the tops of your feet stay comfortable without lace pressure irritating them. The upper is coated with a treatment to help keep you dry, preventing rainwater from entering the shoe whilst simultaneously allowing moisture and vapour build-up from inside the shoe to escape so you stay fresh and focussed. A gusseted tongue adds another layer of defence against the elements, blocking out adverse weather conditions as well as any debris on the road. A traditional lacing system helps securely anchor the shoe to your foot, so you have greater stability and control.

A full-length platform of React cushioning resides underfoot to deliver feathery durability plus smooth responsiveness. To produce this startlingly lightweight and springy midsole, crafted from synthetic rubber, Nike listened to the voice of the athlete. Their in-house sports research lab plugged footstrike data into a proprietary algorithm that determined how much cushioning was needed and where. They simulated testing on approximately one hundred possible shoe geometries to quickly determine the handful they knew would work best for most runners and then merged the science with an elegant design, intended to feel like a slipper on a mattress. The reactive nature of this clever midsole material means it absorbs impact and then expels it back out for a bounce-like effect. This energy-return technology reduces the use of superfluous muscle power, diminishing fatigue and enhancing performance, keeping you going for longer. Soft, generous and substantial, React will spare your joints as you strike down onto hard, unforgiving concrete and infuse every stride with the kind of zealous power that is often elusive in the running world. Embedded within the generous React platform, and complementing its reactive nature, is a Zoom Air unit in the forefoot. This low-profile midsole feature combines pressurised air with internal fibres to deliver responsive cushioning that springs back fast, so you can move faster. Twice as big as previous versions, the unit delivers more bounce with every step. It's top-loaded to be closer to your foot for better responsiveness as you move through the gait cycle.

The Storm-Tread outsole provides excellent traction in wet weather conditions. It features textures inspired by all-winter tires, so you know they can tackle whatever weather your run takes you into. Micro grooves grab the road, while multidirectional shapes help shed water for direct contact with the pavement, helping you to find traction and grip for an ultra-responsive, confident run - no matter the conditions.
