Summary
A lighter, more versatile stability shoe for flat-footed runners who don't need the full support of the Kayano. Ideal for moderate overpronation and faster training paces.
The most motion-control shoe in the Brooks lineup, built for runners with severe flat feet who need maximum structure. Heavier than the Adrenaline but offers noticeably more arch support.
Pros
- Lighter and more responsive than the Kayano while still offering stability
- Recommended for flat feet with moderate (not severe) overpronation
- More versatile for varied training paces
- Consistently mentioned alongside Kayano as a top flat-feet pick
- Maximum motion control for severe overpronation
- Preferred over Brooks Adrenaline by users needing more support
- Durable construction holds up over high mileage
- Recommended alongside ASICS Kayano as a top-tier flat-feet option
Cons
- Less arch support than the Kayano — not enough for heavy overpronators
- Can feel squishy at faster paces per Wirecutter testing
- Fewer width options than some competitors
- Significantly heavier than most running shoes
- Not suitable for speed work or racing
- Bulkier fit may feel uncomfortable for mild flat feet
Our take
The GT-2000 is the Kayano's more nimble sibling — if your flat feet are manageable and you want something you can actually pick up the pace in, this is the smarter buy.
If the Adrenaline isn't cutting it for your flat feet, step up to the Beast — it's the shoe flat-footed runners reach for when they need serious motion control, not just mild stability.
