ASICS GT-1000 15 Review 2026: Budget Support Trainer Tested

The ASICS GT-1000 15 Has Launched

The ASICS GT-1000 15 is now available, and it turns out our preview coverage called it correctly: this is an iterative refinement of the GT-1000 14 rather than a ground-up redesign. It keeps the same accessible price point and stability-focused ride that has made the GT-1000 line a go-to daily trainer for triathletes who overpronate mildly, with a more durable outsole and a redesigned upper as the headline changes.

Verified Specs

• Price: £115 UK ($110 US)
• Weight: 278g (men’s), 242g (women’s)
• Heel-to-toe drop: 8mm as advertised by ASICS (independently lab-measured at 9.9mm by RunRepeat)
• Stack height: 35.0mm heel / 25.1mm forefoot
• Midsole: FF Blast foam — the same formulation as the GT-1000 14 — with PureGel cushioning added at the heel
• Outsole: Full-length AHARPLUS rubber, an upgrade from the GT-1000 14’s standard AHAR compound, aimed at improved durability
• Stability system: 3D Guidance System, with a wider platform than the 14 (119.4mm forefoot / 99.8mm heel)
• Sockliner: OrthoLite
• Surface: Road

Who Is It For?

The GT-1000 15 is built for beginner and recreational runners who overpronate mildly and want a dependable everyday training shoe. For triathletes, it works best as a general training shoe for easy runs and long slow distance sessions rather than a race-day flat — the 3D Guidance System stability setup suits athletes who find fully neutral shoes cause knee or hip discomfort after brick sessions.

GT-1000 15 vs GT-1000 14: What Changed?

The FF Blast midsole and PureGel heel unit carry over unchanged from the 14. The real upgrade is the outsole: full-length AHARPLUS rubber replaces the standard AHAR compound and measurably improved durability results in independent testing. The upper has also been redesigned for breathability, and the platform is now slightly broader for extra stability. Weight has crept up slightly (278g vs the 14’s 230g), which is the trade-off for the wider, more durable build. If you already own and like the GT-1000 14, the 15 is a like-for-like replacement rather than an urgent upgrade.

Is It a Good Triathlon Training Shoe?

RunRepeat’s independent lab testing scored the GT-1000 15 83/100, praising the outsole durability and the broader, more confidence-inspiring platform, while flagging limited energy return through the heel and a flat ride that isn’t suited to speedwork or longer distances. That matches how it fits a triathlete’s kit bag: it’s a durable, protective shoe for brick sessions, easy runs and high-volume weeks — not a race shoe. Pair it with a lighter race-day shoe like the ASICS Metaspeed Sky or Superblast and use the GT-1000 15 to build the fitness you’ll spend on race day.

Buying Tips

• True to size — stick with your usual ASICS running shoe size.
• If your priority is outright durability over 50-60km training weeks, the upgraded AHARPLUS outsole makes the 15 worth the small weight increase over the 14.
• Not on Amazon UK yet — if you want an affiliate-tracked purchase today, the ASICS GT-1000 14 (women’s, Amazon UK ASIN B0G2TGSD1P) uses the same midsole platform at a lower price while stock lasts.
