Sponge Crater. A-COLD-WALL* helps reimagine a new Converse designed silhouette that pushes the limits of style and wearability with a less-is-more ethos. The flat-knit upper helps promote breathability and the spandex collar, pull tabs and exaggerated heel kick enhance ease of entry. The avant-garde design comes to life through a thoughtful production process delivering a bold new silhouette.
