Joma Sima 25

In the world of trail running, finding shoes that deliver comfort, protection, and reliable performance without breaking the bank can feel like a tall order. But the Joma Sima 25 proves it’s possible to bring all of these elements together in one well-rounded model.

Design / Aesthetic

From the very first outing, the Joma Sima 25 feels like it was made for the trail — especially if you’re clocking in mid-range distances (think 20 to 30 km) on terrain that’s challenging but not extreme. The upper is crafted from breathable Jacquard mesh, reinforced with heat-sealed overlays at the toe and along the sides. It’s the kind of design that gives you peace of mind when you’re weaving through brush or dodging rocky patches.

There are no annoying seams to rub you the wrong way either. The upper is smooth and thoughtfully bonded, while plush padding around the collar and tongue keeps things snug without being suffocating. At roughly 304 grams, it’s not featherweight — but it’s not clunky either. Most of that heft comes from the generous cushioning and extra protection, which you’ll probably be thankful for after a few hours on the trail.

Performance / Tech

The FOAM REACTIVE midsole is the heart of the Sima 25. It delivers consistent shock absorption that holds up well over time — not pillow-soft like a Hoka, but a firm, grounded ride that’s still gentle enough on your legs to keep you going for the long haul. The 7mm drop strikes a good balance: versatile enough for beginners yet low enough to maintain decent trail feel. A built-in TPU shank adds torsional rigidity right where you need it, keeping your midfoot stable on unpredictable surfaces without locking your foot down.

Fit, Comfort & Build

The fit is pleasantly secure without feeling claustrophobic. The seamless JOMA SPORTECH bonding system eliminates the usual hotspots you get from traditional stitched overlays, and the thermosealed toe cap adds a layer of real-world protection without stiffening up the forefoot. The collar and tongue padding are well thought out — lock-down is confident, even without cinching the laces super tight. Wide-footed runners may want to try before committing, as the fit leans slightly on the narrower side through the midfoot.

Traction / Outsole

When it comes to grip, the Sima 25 doesn’t mess around. The DURABILITY rubber outsole features multi-directional lugs that bite well into a wide variety of surfaces — dry dirt, damp mud, scrambly rock, or soft gravel. Uphill, downhill, sharp turns — the traction holds up. That said, on highly technical terrain with exposed roots and tight switchbacks, the outsole can feel a touch rigid compared to more aggressive trail-specific shoes. Best suited to low-to-moderate difficulty trails.

Things to Consider

The Sima 25 is aimed squarely at the mid-range trail runner — and that’s exactly its sweet spot. It’s not designed for extreme mountain running or ultra-technical skyrunning routes. Runners transitioning from minimalist shoes may need an adjustment period given the moderate stack and 7mm drop. And while the shoe is available in both men’s and women’s specific versions, those with wide feet should try for sizing before buying online.

Final Verdict

The Joma Sima 25 is a genuinely impressive trail shoe for the price. Solid construction, reliable cushioning, and trustworthy traction for runners who want a dependable daily trainer for moderate trails — without spending a fortune. If you’re a recreational trail runner looking for a well-built, no-nonsense shoe that covers the basics exceptionally well, the Sima 25 deserves a serious look.
