The Nike EXP-X14 ‘Wolf Grey’ sneaker brings a classic colorway to the performance-driven silhouette, with EXP as an abbreviation for ‘experiment’ and X14 referring to the internal code for the Nike React cushioning technology. Created with the Nike Zoom and Epic React styles in mind, the EXP-X14 boasts breathability and lightweight durability with React technology and a sturdy foam midsole. The Wolf Grey silhouette is decorated with visible Flywire cables and a translucent overlay.
