Puma was flooded with traffic today as customers tried to purchase a pair of the newest Creepers.

The new collection includes three Puma suede styles in ice cream flavor-inspired colorways.
The collection is inspired by the contrasting colors of the ocean and ecosystem — blue, pink and aqua.
The new six-story building in Herzogenaurach will house about 550 employees and is set to be completed by spring 2018.
