Nike Air Zoom Pegasus 42 Women's Running Shoes

Responsive full-length cushioning sculpted to energise an icon. Experience power in every stride thanks to the propulsive feel of a curved, full-length Air Zoom unit and a ReactX foam midsole.

Engineered Mesh Upper

The upper of the Pegasus 42 has been crafted from an engineered mesh that's even more breathable than the previous model, while having a softer feel against the skin, for an irritation-free fit the moment you put them on. Perforations in the fabric encourage air to flow freely around the shoe, releasing built-up heat, creating a healthier environment for your feet to thrive in. Just like previous versions, the mesh is designed to stretch, moving with your foot as though the shoe was made for you, while providing a secure hold as you move through the gait cycle. Nike has made the toebox wider than the Pegasus 41 using the new MR-10 2.0 Last, offering extra room for your toes while maintaining the shoe's great fit. Completing the upper is a traditional lacing system that locks down the midfoot, reduces in-shoe movement and enhances support for distraction-free strides.

Nike ReactX Midsole

Providing the same soft, lightweight feel you know and love, Nike uses ReactX foam to deliver a responsive ride while remaining durable for a long-lasting shoe. The foam's reactive nature means it absorbs impact when hitting hard, unforgiving surfaces below, then expels it through your next stride for a bounce-like effect, sparing your joints and reducing the risk of injury in the process. This energy-return technology slows down fatigue while enhancing performance, keeping you running for longer. Updated for the 42, Nike has used a full-length Air Zoom Unit. This low-profile midsole feature combines pressurised air with internal fibres to deliver responsive cushioning that springs back fast so you can move faster. Using a full-length unit, Nike provided a more responsive and energetic ride than ever before, letting you run further, faster, before fatigue sets in. The shoes offer greater toe spring than the previous model, due to the updated silhouette and increased curve in the toe box. This, combined with the extra room, enhances stability and, with the updated Zoom Air unit, allows you to move more quickly than before.

Rubber Outsole

Using an all-new waffle-inspired rubber outsole, the Pegasus 42 ensures enhanced traction in dry and wet conditions. The durable rubber provides a strong grip, protecting itself from damage and protecting users from losing control and slipping. The rubber is placed in high-wear areas, including the full forefoot and sections of the heel, to increase durability and resist heel-strike trauma. The rubber has been removed in the midfoot to reduce weight for a lighter feel. The new flex groove design allows the foot to move more naturally through the gait cycle, while increasing surface area for better grip and traction on the surface below.
