Popular Running Shoe Comparisons
The PUMA Velocity NITRO 4 and PUMA Velocity NITRO 3 share the same family name, but they feel like two very different shoes on foot. The Velocity NITRO 4 is significantly lighter and built on a full slab of modern A-TPU foam, which provides a more energetic and bouncy ride with improved cushioning, especially for heel strikers. The Velocity NITRO 3 uses a dual-density setup with NITRO over an EVA carrier, and that EVA layer makes it feel slightly duller, less cushioned, and much less lively underfoot. In practice, the midsole change is the main reason the Velocity NITRO 4 feels so refreshing and competitive in today's market, whereas the Velocity NITRO 3 comes across as a more traditional, slightly duller trainer. Both shoes offer similar overall stability, but if you want a daily trainer that actually feels agile and fun, the Velocity NITRO 4 is a clear upgrade.
