Adrenaline GTS 25 vs ForeverRun Nitro 1

The Adrenaline GTS 25 is Brooks doing what Brooks does best: a dependable stability running shoe built to log miles, week in and week out, without any drama. This is the shoe you reach for when you want support that stays out of the way. The GuideRails system only steps in when your stride starts to collapse inward, so if you run neutral it barely registers, and if you overpronate it gently keeps you honest. With a 10mm drop and a 37mm heel it sits squarely in the traditional daily training shoe camp, aimed at runners who want structure and a familiar, protective ride rather than bounce or speed. At 301g it is not light, and it never pretends to be a tempo shoe. What you get instead is consistency. In our view this is one of the safest first-stability-shoe picks in the UK, and a reliable rotation workhorse for the runner who just wants to get out the door and train.

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.
