Nike's ACG line is back with another outdoor-ready silhouette coined the Mountain Fly GORE-TEX that's built to tackle any condition. Up top, A GORE-TEX membrane provides industry-leading waterproofing, which is coupled with durable hard rubber for heightened protection. Drawing inspiration from the Vaporfly 4%, the pair boasts a carbon fibre plate within the React midsole to protect you from hard, uneven surfaces. There's also a heavy-lugged outsole to stop you from slipping on challenging terrain. CT2904-001, Textile & Synthetic Upper/Synthetic Sole.
