ASICS Gel Trabuco 12 First Run Review: Protection and Comfort for Long Trail Miles
A big-stacked trail shoe with FF Blast foam, rearfoot Gel and aggressive grip. Our first impressions after 4.5 miles of mixed terrain in the New Forest.
Introduction
The ASICS Gel Trabuco 12 arrives with a serious stack for a trail shoe: 36mm in the heel, 28mm in the forefoot, and an 8mm drop. At 312g (11.3oz) in a UK men’s 8.5, it sits in a competitive space alongside shoes like the Merrell Agility Peak 5 and Speedgoat 5, and in the UK it retails at £140. After a first run over 4.5 miles of genuinely mixed terrain, the early signs are very positive.
First Run Impressions
The test run covered road, groomed gravel paths, grass, hard forest trails with tree roots, and some seriously deep, boggy mud. The Trabuco 12 was run on tired legs after a 30-mile day, which made the step-in comfort stand out immediately. This is a roomy, welcoming shoe from the first moment you put it on, with none of that “work your way into it” stiffness some trail shoes have.

The midsole is the star here. There is a generous wedge of FF Blast foam, the same family of foam used in ASICS road shoes like the Novablast, paired with the brand’s adaptive guidance system and a rock plate. Rearfoot Gel units soften heel landings, which was noticeable on this run with heavier, more rearward foot strikes. The platform feels cushioned but not overdone: soft enough to protect on road sections, firm enough that the shoe does not squish and wobble on softer ground.
Grip and Traction Across Mixed Terrain
The outsole uses an aggressive layer of ASICS Grip rubber, and it coped well across everything thrown at it, including deep, slippy mud. On climbs there was good traction with no heel rubbing, and rolling descents felt secure.

There is a trade-off worth knowing about. That grip is a little sticky on tarmac, so if your runs are mostly road-to-trail, something with shorter 2.5 to 3mm lugs, like the Merrell MO Flight, may suit better. For genuine trail use, though, the Trabuco 12’s grip is a genuine strength.
Upper, Fit and Comfort
Up top there is a technical mesh upper with plenty of reinforcement around the toe box. The overlays are not rigid, but they add a solid toe stub barrier. The tongue is well padded, the heel collar is plush, and there is a handy heel pull for hanging up muddy or wet shoes plus lace storage to keep loose ends out of the way.
Fit and Sizing
The fit runs true to size for most runners. The toe box has lots of room, a full thumb width of space at the front, and ample volume across the top of the toes. The midfoot hold is secure without being the tightest lockdown around, and the big padded heel collar holds the rearfoot just about on the right side of snug.

Two caveats: there is real structure in the overlays around the little toe area, which could cause rubbing over longer distances for some feet, and the overall fit leans slightly roomy, possibly a touch loose until you cinch the laces down. Wide-footed runners may want to consider going half a size up.
Buying Advice
The Trabuco 12 is aimed at protection and grounded comfort across any kind of trail, and on first evidence it delivers exactly that. It feels light on the foot, balanced rather than clunky, and forgiving enough to suggest real ultra credentials on runnable, rolling terrain. Whether it holds up over 50, 60 or 70-mile days is the next question, but the early signs point that way.

If you have been eyeing shoes like the Hoka Speedgoat 5 or Merrell Agility Peak 5, this feels like it belongs in the same conversation, and at £140 it represents good value for that class of shoe. Go true to size unless you have wide feet.
Conclusion
After the first run, the verdict is a clear thumbs up. The ASICS Gel Trabuco 12 offers a well-balanced platform, genuine cushioning protection, reliable grip and a comfortable, roomy fit. It is a shoe we look forward to spending more long-run hours in, and based on these early miles, it should be on the shortlist for anyone after a protective, long-distance-capable trail shoe.
