Since its debut in late-2018, Nike’s ISPA line has created some of the most striking sneakers to come out of the Beaverton brand. There’s always a focus on the four defining principles – improvise, scavenge, protect and adapt – with each model being highly functional. The Overreact Sandal is no exception. It’s built on the same foundation as the Overreact but stripped back to only what is truly essential. The textured React Foam sole is an ode to improvised traction systems – think the repurposing of bicycle tires as sandals – and perfect for the trails. The upper follows a similar function-first form, using multiple layers to provide structure and protection while allowing the free-flowing of air to keep you cool on the warmer days.
