Adrenaline GTS 25 vs Beast GTS 24

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 Brooks Beast GTS 24 is the biggest, most supportive daily training shoe in the Brooks line, a max-support running shoe built for runners who want to feel held from heel to toe. Think of it as the Adrenaline's bigger, sturdier brother. With a tall 12mm drop and a hefty 340g on the foot, this is not a shoe chasing lightness or speed. It is chasing security. The GuideRails support system keeps your knees and ankles tracking straight when your form tires late in a run, and the plush, protective ride soaks up the miles for heavier runners and heavy overpronators who have never quite trusted a lighter stability shoe. We rate it as a specialist. If you want maximum structure and cushioning for steady road miles and you are not fussed about pace, few shoes hold you like the Beast. If you want any pop or a nimble feel, look elsewhere. This is comfort and control first, everything else a distant second.
