Since making its debut in 2000, Nike Shox R4 sneakers have continued to defy the status quo with their audacious design. This season is no exception, as the Y2K darling embraces its rebellious roots through smooth synthetic leather uppers, inspired by spacesuits and astronaut gear. They feature four compressive columns that lift the heel to create a unique cut out effect. Constructed with synthetic leather uppers and a durable rubber outsole.
