Asics Gel-Cumulus 27 Review: The Smoothest Cumulus Yet

The Asics Gel-Cumulus 27 is the latest iteration of one of the most trusted neutral daily trainers in the running world. Designed for both beginners and experienced runners, the Cumulus series has earned a reputation for reliable comfort, durability, and smooth ride quality. With each version, Asics introduces subtle (and sometimes substantial) improvements, and the 27th version is no different.

This detailed Asics Cumulus 27 review explores what makes this shoe a standout for 2025. We’ve logged over 100 miles in the Cumulus 27 across various conditions—from treadmill to pavement, long runs to recovery days. Here’s how it performed across key categories.

What’s New in the Asics Cumulus 27?

The Asics Cumulus 27 brings several noticeable updates over the previous version:

• FF BLAST™ PLUS cushioning replaces the older FF Blast midsole, offering a more responsive and cushioned ride.

• The redesigned upper features engineered mesh for improved breathability and lockdown.

• A more streamlined outsole reduces unnecessary rubber to cut weight and enhance flexibility.

• Slightly lighter and more refined overall feel.

These tweaks are subtle but effective, pushing the Cumulus closer to premium territory without straying from its approachable price point.

Design and Aesthetics

Asics has taken a sleek, modern approach to the Cumulus 27’s design. The shoe boasts clean lines, tasteful colorways, and a performance-oriented silhouette. Popular colors include steel grey, deep ocean blue, glacier white, and neon yellow—catering to both conservative and bold runners.

The branding is minimal but iconic, with the signature Asics stripe running along the lateral and medial sides. Reflective accents around the heel make it nighttime-friendly, a thoughtful safety touch.

⭐ Verdict: One of the best-looking Cumulus models to date.

Upper: Breathable & Secure

The engineered mesh upper offers a soft, sock-like fit that hugs the foot without suffocation. Asics has focused on breathability, and it shows—hot weather runs felt surprisingly cool.

Key upper features:

• Padded heel collar for ankle support.

• Tongue is gusseted to stay in place.

• Mesh is dual-layered but ventilated—moisture control is solid.

• Lacing system provides micro-adjustability for a personalized fit.

There’s enough stretch to accommodate slightly wider feet, yet it retains a snug fit for narrow-footed runners.

⭐ Upper rating: 9/10

Midsole & Cushioning: FF BLAST™ PLUS

Here’s where the Asics Cumulus 27 really shines.

The FF BLAST™ PLUS foam is lighter and softer than before. It offers a plush underfoot feel without feeling mushy, making it ideal for long miles or easy recovery runs.

• Heel stack height: 37.5 mm

• Forefoot stack height: 29.5 mm

• Drop: 8 mm

The ride is neutral, stable, and responsive—perfect for runners who don’t need motion control. There’s a hint of bounce on toe-off, thanks to the energetic nature of the new midsole.

Pros:
✅ Great shock absorption
✅ Smooth heel-to-toe transitions
✅ Feels stable on uneven terrain

⭐ Cushioning rating: 9/10

Outsole: Durable Yet Flexible

Asics retained a segmented rubber outsole with high-abrasion rubber in key wear zones, keeping durability high while minimizing unnecessary weight. The exposed foam in the midfoot aids in flexibility and transition.

Even after 100+ miles, there’s only minimal outsole wear—a testament to its build quality.

Traction is sufficient for:

• Wet roads

• Gravel trails

• Mild off-road

It’s not a trail shoe, but the grip is reliable on most urban surfaces.

⭐ Outsole rating: 8/10

Fit & Sizing

The Cumulus 27 fits true to size, with a medium volume. Those with wide feet might consider the wide version available in most regions.

Key fit points:

• Generous toe box

• Secure midfoot hold

• Locked-in heel

Testers reported zero heel slippage or hotspots, even on hour-long runs.

Performance on the Run

Whether you’re logging 5Ks or half marathons, the Cumulus 27 delivers a balanced and forgiving ride. It’s ideal for:

• Daily training

• Recovery runs

• Long slow runs

• Beginner racing

It’s not a speed shoe, but it can handle tempo runs if needed. The FF Blast+ foam gives it just enough spring to stay lively without pushing into high-performance racer territory.

Transitions are silky smooth, especially for heel and midfoot strikers. Forefoot strikers may find the ride slightly less dynamic, but still pleasant.

Weight

• Men’s US 9: Approx. 9.2 oz (260g)

• Women’s US 8: Approx. 8.1 oz (229g)

The new midsole helped shave off a few grams, making the Cumulus 27 feel light on foot while retaining enough foam for high-mileage comfort.

Durability & Longevity

The materials and construction suggest the Cumulus 27 should easily last 400–500 miles, depending on your gait and running surface. The upper stitching, glued overlays, and outsole rubber show minimal breakdown even with daily use.
