At first look, the Inov8 Trailfly appeared unlikely to carry as much as the brutality of ten-hour days on tough terrain. However after over 600 whole miles, I can confidently say that this is among the greatest footwear I’ve ever worn when it comes to ruggedness, breathability, responsiveness, and luxury.

The Trailfly is supremely grippy, cushioned, and comfy, hugging your heel and leaving a great deal of room in your toes. 600 miles later, my pair remains to be going robust.

Circumstances of Evaluate

The Trailfly arrived a number of weeks earlier than I used to be set to stroll the 100+ miles I had left to finish the Arizona Path, adopted by a deliberate one-month hike on the Appalachian Path. I educated in them on native trails in Minnesota which can be steep, eroded, rocky, and muddy, then wore them completely on each trails (so in Arizona,  Georgia, North Carolina, Tennessee and a wee little bit of Virginia) for a complete of 600+ miles. 

Supposed Use

Out of the field, the footwear look far much less rugged than they’re. However they proved well-fitting and comfy and dealt with fantastically, particularly when working up and down the stupidly steep and slippery hill on the Minneapolis Ski Soar the place many people within the Midwest prepare for “actual” mountains.

The Trailfly is beneficial for precisely that: it’s a trail-running coaching shoe meant for on a regular basis use and possibly a potential longer race.

Boomerang Footbed: The “Boomerang” footbed is a cushioned insole that Inov8 claims provides the wearer quicker and bouncier outcomes whereas cushioning every footfall. Personally, I discovered the insoles a bit too comfortable, particularly when mixed with the high-cushion foam midsole, so I changed them with a firmer pair of Superfeet.

Airmesh Higher: The higher is well-ventilated and drains extraordinarily quick. Whereas Inov8 recommends these footwear for dry circumstances, my pair noticed intensive rain, river crossings, and quite a lot of mud. The Airmesh managed effectively in all circumstances, drying shortly and holding its form.

The footwear additionally felt extraordinarily gentle and springy, essential when in your ft all day. 

Anatomical Match (Accessible in Broad): As a result of I’ve arthritic toes and my ft are huge, I usually order barely bigger than my dimension. Whereas that is my first take a look at of the Trailfly and I can’t make a comparability, Inov8 redesigned the slot in 2024 to be tighter on the heel and wider on the toes. Typically this made it tough to shove my heel inside them, however as soon as fitted, they felt like a second pores and skin. These footwear can be found in Broad.

Met Cradle Strips: The Met-Cradle strips maintain the mesh uppers in place and supply additional safety. It helps that the shoelaces (which get pulled and tightened every day) final simply so long as the footwear.

Rock plate: The rock plate and toe guards protected my ft from inevitable stubs, but I nonetheless felt in contact with the bottom as if in climbing footwear.

Graphene Grip: Inov8’s authentic declare to fame, the graphene lugs are designed and organized for optimum efficiency (translation for a runner: velocity, pointless for this middle-aged hiker). That being mentioned, they clung effectively in every kind of circumstances together with moist rock, mossy and muddy surfaces, in addition to whereas crossing streams and on free stones whereas descending. 

And in spite of everything these miles, the lugs had been solely calmly worn. Inov claims the inclusion of graphene within the rubber outsole will increase their sturdiness, and I’m right here to formally affirm this.

The shoe typically held collectively (minus some loosening of the rock plate itself on the heel), and I think about I’ll nonetheless get at the very least one other 100 miles out of them.

Inov8 Trailfly Cons

Runs small: The Trailfly runs barely small, so I extremely suggest sizing up a half-size.

General Worth

muddy pair of grey and blue inov trailfly shoes with laces undone

Seven years in the past, I ran an ultramarathon in the UK known as “The Fellsman.” It’s named for the hills – or fells – of the area, that are run by “Fell Runners,” most of whom launch their our bodies straight down unimaginably steep, tussocky and uneven slopes at unbelievable speeds. I’m constructed to ascend, not descend, so I misplaced plenty of time in that race on these wild descents.

Inov8 was based over 20 years in the past for and by these crazy-strong Fell Runners. However I see now that their intention was to assist us lowly wannabes obtain some semblance of “stream” after we transfer (even when mountaineering and never working) the place we not take into consideration our gear or our our bodies, however slightly merely transfer as we’re alleged to.  

As my ft have aged, changing into extra oddly formed with arthritis, I’ve had an especially troublesome time discovering footwear each huge sufficient and sturdy sufficient for the a whole lot of miles of tough terrain that I hike. 

I imagine I’ve discovered simply that good shoe within the Inov8 Trailfly.
