PUMA Deviate NITRO Elite 4 vs Fast-FWD NITRO Elite 2

The PUMA Deviate NITRO Elite 4 and PUMA Fast-FWD NITRO Elite 2 are two super shoes by the same brand, but they serve very different purposes. The Deviate is the more versatile and approachable option for most runners, with much more cushioning, a more responsive ride, a more forgiving fit, and enough protection to handle everything from shorter races up to the marathon. The Fast-FWD is significantly lighter and more focused for 5K and 10K racing, with a lower, firmer, more stripped-back ride that feels closer to a modern racing flat. That said, it gives up a lot in protection, comfort, and range, so it's not suitable for long runs or longer races.
