PUMA Deviate NITRO 3 vs Deviate NITRO 4

The PUMA Deviate NITRO 4 and PUMA Deviate NITRO 3 are two iterations of the same super trainer, but the newer version does a better job defining itself as the faster, more performance-focused option. The Deviate NITRO 4 is lighter, feels more energetic underfoot, and pairs its moderate drop with a snappier forefoot, making it better suited to workouts and even shorter races. The PUMA Deviate NITRO 3, by comparison, sits a bit higher and feels more protective, giving it a slightly more cushioned character. If you want the more efficient plated trainer, the Deviate NITRO 4 makes more sense, but if you prefer a bit more buffer and protection underfoot, the Deviate NITRO 3 still has its appeal.
