Kailas Fuga DU vs Fuga EX2: Two Trail Shoes With Very Different Personalities

A close look at the wide-platform Kailas Fuga DU and the more affordable Fuga EX2, with what each does well and where they fall short.

Introduction

Kailas has been building out an increasingly serious trail running lineup, and two models from that range stand out for very different reasons: the new Fuga DU, a distinctive wide-platform shoe aimed at longer efforts, and the Fuga EX2, a more affordable shoe that has quietly proven itself over multiple runs. Here is how they compare and who each one makes sense for.

Kailas Fuga DU: First Look

The Fuga DU is one of the more expensive shoes in Kailas’s trail lineup at around 200 euros, roughly 175 pounds in the UK, and it brings a lot of shoe for that money. In a UK nine it weighs a reasonable 318 grams, with an 8mm drop and a deep cushioning stack of 35mm at the heel and 27mm under the forefoot.

The outsole uses Vibram Megagrip Light Base rubber, a compound well known for grip on rock and wet rock, with a lug layout shaped differently from the Fuga Pro 4S. The midsole uses an echever dual compound construction similar to the Pro 4S but with noticeably more of it, giving a much deeper stack of cushioning. The two-section quick lace system with a lace hook carries over from other Kailas shoes, and the lace pocket on the tongue has been repositioned to sit further from the laces, making it noticeably easier to stow than on the Fuga Pro 4S or Fuga EX2.

What sets the DU apart is its design. The midsole platform is ultra-wide, with a forefoot measuring 125mm across, one of the widest forefoots seen on a trail shoe. Kailas claims it delivers 15 percent more grip and more stability on rugged trails. There is also a 3D TPU heel cradle for lateral and medial support on uneven ground, which forms part of a four-point gaiter attachment system. The upper is a lightweight, breathable jacquard engineered mesh with an internal sandproof lining, and the matching gaiters fit so securely that they are easy to forget they are attached. Combined with the sandproof liner, this looks like an ideal setup for sandy terrain such as dune running.

On the Trail: How the Fuga DU Performed

Testing took place in genuinely harsh conditions: heavy rain, deep mud, and wet leaves covering slick roots and wet rock. The Vibram Megagrip Light Base outsole handled it all well, with solid grip on rocky trails, wet tarmac, and greasy tree roots, which is a demanding combination for any outsole. On wet muddy grass there was occasional lost traction, and the lugs measure around 4mm in depth, so a little more lug depth would help in really boggy conditions.

The cushioning feels excellent straight out of the box, and an exaggerated rocker in the midsole rolls you efficiently through to toe-off. The fit is secure and held well through the midfoot and heel thanks to the double closure quick lace system, with a Salomon-like feel. Be aware that they size up quite long, and the toe box tapers fairly narrowly, which could become uncomfortable for wider feet on longer runs.

Things to Consider Before Buying the Fuga DU

The wide platform is the defining trade-off. It makes the shoe feel stable and planted, but also a little bulky underfoot. When the pace picked up on more technical sections, it did not feel particularly lively or responsive. This is a shoe designed for longer efforts at a steady pace, where a comfortable midsole matters more than agility. One practical quirk worth knowing: that ultra-wide forefoot makes these genuinely difficult to drive in.

Kailas Fuga EX2: The Proven All-Rounder

The Fuga EX2 has already proven itself over repeated outings, performing well from its first run and seeming to get better with every use. It shares the same quick lace system and lace hook as the rest of the range, and the fit suits a similar foot shape to the Fuga DU. The key difference is its price: it happens to be the more affordable shoe of the models tested, and it was ultimately the favorite, delivering the best overall performance and the best fit. For runners who want proven trail performance without the premium price of the DU, the EX2 is the more balanced pick.

Which One Should You Buy?

Choose the Fuga DU if you run long distances at a steady pace, value maximum cushioning and stability, or want an integrated gaiter and sandproof liner system for sandy terrain. Its wide platform and deep stack are built for comfort over hours rather than speed over technical ground. Choose the Fuga EX2 if you want a more affordable, nimbler shoe with a proven track record and the best all-round fit. With more miles still to come on the DU, the EX2 remains the safer bet for most trail runners today.

Conclusion

Both shoes show why Kailas is becoming a name worth watching in trail running. The Fuga DU is an ambitious, comfort-first design with standout grip and a unique gaiter system, while the Fuga EX2 offers proven performance at a friendlier price. Match the shoe to the terrain and effort length, and either can be a rewarding pick.
