The Nike Pegasus Premium 'White Metallic Silver' is highlighted by a ZoomX foam midsole with a sculpted Zoom Air unit that runs the full length of the foot and springy ReactX foam in the heel. Underfoot, a modified waffle-traction outsole utilizes high-abrasion rubber for durable grip. The upper features white circular knit construction with breathable mono mesh paneling and the same dynamic midfoot system used throughout the Pegasus line.
