GT-2000 15 vs ForeverRun Nitro 2

Previous GT-2000s were the stability shoe you bought because it was sensible. Version 15 is the first one reviewers seem to actually enjoy running in. At 252g with 38.2mm under the heel and an 8.2mm drop, it's lighter and more flexible than the GT-2000 14, and the reviews we read agree the ride is livelier and more cushioned than before. The support is mild. A firm, centred platform guides your foot, and there's no hard medial post pushing into the arch. That makes it a daily training shoe for runners who roll in a little, not for severe overpronators. The catch is the fit. The toe box is low and tapered and the heel counter is stiff, so wide or high-volume feet may struggle. UK reviewer Fordy Runs rates it an excellent daily trainer, while RTINGS was cooler, finding the cushioning fades on longer runs. We sit closer to the first camp. At £134.99 RRP it's also cheaper than most stability rivals before any discount.

The ForeverRun Nitro 2 is Puma's answer to the modern stability question: hold your foot steady without a hard medial post, and cushion it enough to still feel good at the end of a long run. It is a road stability trainer built for higher mileage, with a 38mm heel and 28mm forefoot giving you a genuinely deep, protective platform and a traditional 10mm drop that most heel-strikers will settle into fast. The support comes from a wider, structured build and Puma's RunGuide sidewalls rather than a firm post, so it guides rather than corrects. At 295g it is not light, and you feel that. This is a shoe for steady, controlled miles, not a shoe you will want to pick up the pace in. If you overpronate mildly or just want a stable, cushioned daily workhorse that stays composed when you are tired, it earns its place. If you are chasing lighter, springier stability, look at the newer wave of soft-support trainers instead. It replaces the ForeverRun Nitro 1 and keeps the same job description.
