Asics Gel Cumulus 15 Product Review

Short Take

The Asics Gel Cumulus 15 is a tried and true neutral trainer – a no-frills shoe that will simply get the job done.

Big Updates

  • Increased Underfoot Plush: This update offers a softer and cushier underfoot feel than its predecessor.
  • More Gel: Asics upped the amount of Gel in both the heel and forefoot for greater impact protection.
  • Welded Overlays: Seamless overlays around the midfoot reduce stitching within the inside of the shoe.

Road Test

When it comes to everyday neutral trainers, Asics’ Gel Cumulus series is a chart-topper in popularity and following. Though a reliable shoe, the 14th version of the shoe seemed to hit a bit of a slump, receiving criticism from longtime fans for a number of reasons, including a ride that felt stiffer and firmer than fans really liked. Luckily, Asics listened, and addressed the predominant concerns in the Cumulus 15.

Testers reported a softer and more protective ride in the newest Cumulus, especially in the forefoot. The reason? A number of factors come into play, ranging from increased shock absorbing Gel in both the heel and forefoot to an upgraded sockliner delivering a premium underfoot feel. Either way, if you felt the Cumulus 14 was too firm, you’ll be pleased to try a softened up 15.

Fit-wise, the Cumulus 15 doesn’t differ much from the prior model. Expect a roomier forefoot to accommodate a greater range of foot shapes, and a plush, padded heel collar for security. The use of seamless overlays around the midfoot does reduce interior stitching and irritation on the foot.

We see this shoe as an improvement over its predecessor, going back to the cushioned feel that Asics’ trainers are known for. If you’re looking for a dependable trainer to carry you over the long miles, the Cumulus 15 is a worthy shoe that deserves a look.

Runners Say


“Asics did a good job dialing in the cushioning on this one. It’s soft enough to be comfortable but still has a pretty responsive feel.”


“This shoe has a fairly roomy fit through the mid and forefoot – runners with high volume feet should take note.”


“The Cumulus continues its run as a dependable trainer. This would be a top recommendation for neutral runners just looking for a solid high mileage shoe.”
