GT-2000 15 vs ForeverRun Nitro 1

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 is Puma's answer to the big, dependable stability trainer, and it lands squarely in that daily-mileage space rather than trying to be fast. This is a supportive road running shoe built for runners who want their legs held steady over long, repeated miles. At 274g it is a substantial shoe, and you feel that weight, but you also feel the reward: a stable, planted platform with a 10mm drop that suits heel and midfoot strikers alike. Puma leans on structure rather than a firm medial post you can feel, so the guidance is there without shouting. If you have bounced off aggressive stability shoes like the Asics Gel Kayano in the past, this is a gentler take on the same idea. We rate it as a genuine long-run workhorse for overpronators and heavier runners who value durability and calm underfoot over pace.
