Introducing NTRVL. The PUMA x JEFF STAPLE collection adapts to each activity in your day with multifunctional pieces and premium materials. A design tour de force and confirmed sneakerhead, Staple helps you take on the most un-routine days from work, to workout, to casual evening out with NTRVL. The latest IGNITE runner – and its redesigned tooling – get the premium Staple Design treatment with its signature color palette and material play. Each shoe is divided into two parts – with opposite color blocking applied to the medial and lateral sides.
