The day after Christmas after I slipped on the Inov8 TrailFly Zero V2 ($175) footwear for his or her first out-of-the-box path journey — for iRunFar reviewer Annie Behrend’s 15-mile birthday run — I knew immediately that Inov8 was critical about analysis, design, and executable enhancements. With this new model of the TrailFly Zero, Inov8 made a smart working shoe tangibly higher. All of the minor particulars that have been a bit off with the unique at the moment are a non-issue, a factor of the previous. The match and really feel are each perceptibly dialed. On this primary run, I ran the TrailFly Zero V2 in mud, rain, and snow, in addition to on comfortable singletrack and dust roads. They nailed it. After all, they yearned for extra rocks and hardpack, however they embraced the variability.
The TrailFly line affords one thing distinctive and satisfying for almost each sort of runner. There’s the TrailFly Zero line, the Inov8 TrailFly Pace (assessment), the Inov8 TrailFly Max (assessment), and the Inov8 TrailFly (assessment) for day by day coaching. Every of the fashions in V2 are available in a regular or broad match (the unique Pace wasn’t supplied in broad), exhibiting that Inov8 is studying the wants of the better path working group. Though you may’t fulfill everybody, the corporate’s mission of pure foot operate and floor connection retains it actual and regular in an ever-changing and ever-growing market.
I ran within the unique model of the TrailFly Zero for months — ensuing within the back-to-back testing of the 2 variations of the TrailFly Zero sequence. The unique TrailFly Zero’s rhythm is being a gradual coach for hardpack path working. A particular throughline from the unique to the upgraded V2 is a reiteration of its reliability and regular efficiency on harder-packed and rocked surfaces, whereas not tentative on extra technical and softer terrain. It’s a shoe you don’t have to fret about as a result of you understand it may well deal with the weekly and quotidian runs — all yr. Comparatively, the TrailFly Zero — each variations — experience equally to the TrailFly Pace and the Topo Pursuit (assessment) with their footbed, type, and anatomical foot form.
Because the title suggests, the TrailFly Zero V2 is a zero-drop path shoe. It rides with a 22-millimeter stack top heel to toe, with a slight rocker at every finish. It has a claimed weight of 10.0 ounces (285 grams) for a U.S. males’s 9 — not gentle, not heavy. A zero-drop stack could also be a tough promote for some people who aren’t biomechanically tailored, however for these runners with lower-limb endurance and an appreciation for down-trending minimalism, it’s a catch and keeper. Nonetheless, I usually suggest a zero-drop path working shoe for many who are prepared, robust, and sensible about their coaching. On the subject of zero-drop footwear, the TrailFly Zero V2 is an effective place to start out. The midsole and outsole present appropriate consolation with out forgoing the bottom connection and pure experience. The toebox honors broad toe splay and pure foot motion, however now with a extra attuned total match and locked-in expertise.

Inov8 TrailFly Zero V2 Higher
A lateral view of the Inov8 TrailFly Zero V2.
The Inov8 TrailFly Zero V2 skilled obligatory and notable upgrades. The redesign components have been primarily targeted on the development of the higher — how the runner experiences the outer shell and the way the higher interacts with the atmosphere. These adjustments made a substantial distinction not just for the elevated reliability of the shoe, but in addition for the shoe’s efficiency.
The TrailFly Zero V2 presents itself as a no-nonsense path runner. Regardless of its doable lack in rapid aesthetic enchantment, in contrast to the stealth TrailFly Pace with its blur of shade, the higher undoubtedly performs its jobs — safety and lockdown. It’s an unassuming workhorse. And whereas the higher’s all grey shade was chosen purposefully, it fondly grew on me, and it goes effectively with all the things. The TrailFly Zero V2 boasts not solely beefier toe bumper safety but in addition thicker overlays on each the medial and lateral facets of the shoe. These adjustments are profound for its total sturdiness, and for the way it suits and performs through the gait cycle.
The Met-Cradle TPU overlays neatly tie into the lacing system for enhanced midfoot to heel lockdown — a much-needed improve. The unique model suffered from unfastened heels and a voluminous midfoot, usually giving solution to undesirable house and motion. The overlays are doubly layered in some spots for further abrasion resistance and higher toughness. Within the newest model, designers carved out holes within the toe bumper for higher drainage. Since this shoe runs all yr spherical in each sort of climate, these further holes additionally operate as ventilators in tandem with water launch. It could learn just like the newer higher is a fortress, however it’s simply built-in safety.
The higher material is a multi-layer mesh that’s clean on the within and guarded on the outside, and remains to be breathable throughout scorching summer season months. It totally wraps across the forefoot, creating an built-in higher help system and an integrated substrate for the overlay system.
Tongues and laces are all the time an afterthought — so it appears. As with most Inov8 footwear, I’m not a fan of their primary, flat, slippery-feeling laces. The tongue on the unique model was virtually a dealbreaker. It was laborious to maintain it in place all through a run. It could duck, sneak, and slide, and for the reason that sizing wasn’t fairly proper the primary time round, the extraneous and unfastened tongue was amplified. Inov8 is normalizing sizing throughout all their fashions, however I additionally perceive there’s a distinction in sizing throughout nations and throughout the pond. The TrailFly Zero V2 suits wildly higher, and it comes with a slimmer, smaller, and extra secure tongue.
Inov8 TrailFly Zero V2 Midsole
A medial view of the Inov8 TrailFly Zero V2.
The Inov8 TrailFly Zero V2 has a FlySpeed Professional midsole, which is a supercritical nitrogen-infused EVA foam constructed for enduring help. The heartbeat of a working shoe resides within the design and development of its midsole. That isn’t to say that the totality of the shoe doesn’t matter. It definitely does. Nonetheless, the midsole is central as a result of it’s the rapid floor interfacing with our basis — our toes and core. If it weren’t for the unique TrailFly Zero’s FlySpeed Professional midsole, I most likely wouldn’t have continued working in them.
I discovered the midsole of the TrailFly Zero V2 to be nimble, enjoyable, and a agency consolation. The Boomerang footbed furthers this expertise. As a facet notice, I first encountered a Boomerang insole within the Topo Traverse (assessment) and the Topo Pursuit. I rapidly grew to become keen on TPU compression beads underfoot. This footbed know-how gives enhanced vitality return and likewise sheds water effectively. I do know some runners who insert their Boomerang footbeds into different trainers due to the texture and rebound.
The TrailFly Zero V2 and TrailFly Max each have FlySpeed Professional foam, which is completely different than the TrailFly Pace’s PowerFlow Professional midsole. Totally different footwear. Totally different mission. Totally different midsoles. The TrailFly Zero V2 doesn’t have a rockplate, however I don’t assume it requires that diploma of fortification. The distinction between the 2 midsole supplies is noticeable. The FlySpeed Professional affords extra longevity each to a person run and to the general lifetime of the shoe.
Since I stepped proper into the V2 from the unique after months of testing, I can confidently attest that the agency midsole consolation has remained fixed between the footwear and that the integrity of the FlySpeed Professional midsole has remained regular throughout the miles. Though the shoe isn’t formed to be a velocity monster, the midsole helps sooner miles when wanted, but it surely additionally reveals up for continued underfoot consolation. The low stack top nonetheless permits for first rate floor management and suggestions.
Inov8 TrailFly Zero V2 Outsole
The outsole of the Inov8 TrailFly Zero V2.
The Inov8 TrailFly Zero V2 comes with full protection of the model’s proprietary G-Grip graphene rubber outsole — a good rival of the Vibram Megagrip. Full protection provides weight however boosts safety and enhances long-term sturdiness. In keeping with the model, they’ve enhanced the rubber’s traction for higher grip on moist rocks. For the reason that TrailFly’s mission is rock and hardpack, this improve appears sensible and noteworthy, and maybe pushes it to compete with the outsoles of some VJ footwear. To be examined.
The TrailFly Zero V2 outsole wears the identical structure — together with lug depth — because the TrailFly Pace. On the path interface, there are 4-millimeter multi-directional lugs, enough for tougher surfaces and average singletrack. The grip is notable, and once more, dependable throughout most path circumstances and average climate circumstances. The outsole has seen little or no put on, given the variety of highway miles throughout the shoe’s complete mileage. As I famous within the Inov8 TrailFly Pace assessment, manufacturers like VJ and Inov8 have discovered a solution to improve grip but in addition soften the rubber sufficient to make it amenable for transient highway working.
Inov8 TrailFly Zero V2 General Impressions
A prime view of the Inov8 TrailFly Zero V2.
The Inov8 TrailFly Zero V2 confirmed up able to sort out the paths with a dialed-in match and really feel. Inov8 listened to suggestions throughout the board for the TrailFly sequence, and designers answered with a second era that may endure and face the hardpack life. The higher of the unique actually wanted some fine-tuning — notably with lockdown — they usually nailed it. They took a dependable and endurance-focused path performer and enhanced its sturdiness and total match.
The TrailFly Zero V2 is geared for what the model calls True Pure Working. I’ve taken this to imply foot-focused, gait-supported working with heel-to-toe pure motion. This shoe design works for that, and it additionally helps hard-surfaced path working — entrance nation and backcountry — with endurance and textured terrain in thoughts. It has innate versatility, however shines on the day by day grinds, particularly if zero drop is a regular within the working arsenal.
As a foot-focused energy and conditioning coach, I help and applaud the businesses that acknowledge pure foot biomechanics and in another way formed toes. Inov8 is a shoe firm I inform my athletes and runners about on a regular basis. Their method to launching completely different variations of their base fashions is far appreciated.
