Puma Twentyone At Boxpark.
Puma‘s Twentyone store. Named after the store’s unit number, the concept shop revolves around the number twenty-one: only twenty-one sneaker styles are kept in stock, with inventory refreshed every twenty-one days. Right at the entrance of the store there’s an updated list of available kicks, and a countdown clock lets customers know when a new delivery of shoes are expected to drop. On the twenty-first day when stock is replenished, the store hosts special in-store events or promotions to celebrate the occasion.
