Nike Womens Infinity Flyknit Running Women's Shoes in Athletic Review

Rubber sole. Style#: CD4372-012. Higher foam stack heights provide a softer feel. A wider shape provides a more stable ride, helping release energy with every step. The shape of the Nike React foam midsole is all about zonal performance, providing support for the 3 phases of a runner's stride—flexibility at toe-off, a smooth ride at mid-stance and cushioning at contact. Less material in the shoe means you're closer to the foam, creating a softer, more responsive experience. Increased rubber at the outsole helps deliver traction and durability.
