Boston Celtics’ Kyrie Irving’s signature shoe gets a bright update that works both off the court and on the streets. The Kyrie 4 'Obsidian' features a Dark Obsidian suede upper with mesh in the forefoot for a breathable fit. The basketball sneaker also boasts an oversized, branded Neon Green tongue, a marbled Aqua outsole that bleeds through the midsole like teeth, and an embroidered tonal Swoosh on the side.
