Midfoot and forefoot strikers, be warned, runners say that these shoes felt “neither soft nor protective on impact”—a more evenly cushioned option is the Spartan race OCR. Those looking for a more secure lockdown will find it in the Hoka Challenger 7.

The release of the Ultra G280 completes Inov-8’s ultra-running trifecta—sliding smack dab in the middle of the G270 and the Ultra G300 Max.

While definitely less performance-oriented than the fast (i.e. firm) 270 and less cushioned than the protective (i.e. heavy) 300, the G280 makes up for it by combining the best of both worlds. Its roomy upper and higher stack provides more comfort, while its nitrogen-infused foam makes the shoe lighter and speed-capable.

Just sinks its claws in and sticks

The Trailfly G280 caught everyone by surprise by using an upper that’s atypical in the trail scene: knit. Testers found that this made the shoe more comfortable and voluminous—a godsend for swollen feet during longer efforts.

Despite their initial apprehensions, they also found that it didn’t lack structure, was breathable even in warm temps, and held up well to the wear and tear of 100 km’ worth of trail runs.

Light enough for fast runs

Its roominess, however, may present security issues for low-volume feet. Some runners reported that they had trouble getting a good lis among the best of the best—which unfortunately left an odd-looking “camel-like hump of fabric” over the toe box.

Moreover, “despite being broadest on Inov-8’s fit scale,” one shoe expert found that the toe box was still too narrow that his “pinkie toes still push out the sides of the knit.”

Also quite uncommon to the trail-running world is the Ultra 280’s nitrogen-infused midsole. The foam gave the shoe a unique feel that one user described as “quite soft and energetic” without feeling sloppy.

The G280 feels like two different shoes

Across the width of the G280’s midsole runs an 8-mm groove called the Adapter Flex. This gives the forefoot and heel a feeling of being independent of each other and lends some extra agility for moving across plain terrain.

However, this midsole separation also makes the 8-mm difference in stack heights more noticeable. Experts felt that the heel Light enough for fast runs but was more “capable of sucking up pounding,” while the forefoot had way less protection and “pointy rocks can be felt.”

Bouncy but stable ride

The shoe’s Graphene-Grip “belongs among the who’s who of outsoles,” expressed one critic. Its soft-rubber quality adds to the cushioned feel of the midsole and makes the Trailfly 280 “exceptionally quiet for a trail shoe.”

The graphene enhancement also made the outsole “insanely durable” and, combined with the 4-mm lugs, grippy on most surfaces, “from grassy plains to moist mountains.”

Won’t have you second guessing

According to runners, the Trailfly Ultra G280 has a bouncy-but-never-unstable ride that inspires confidence “even on the most technical of trails,” and runs light despite its ample cushioning.

As summarized by one reviewer, it’s ”the perfect middle ground” for daily training, faster short runs, and longer races and adventures.
