The RocFly sneakers are extremely comfy to put on day in and day trip with a reasonably heavy pack. The sneakers wanted minimal break-in time. The higher felt a little bit stiff at first however relaxed and obtained extra comfy as I wore them. Cushioning on the heel and on the tongue saved them comfy even when laced down tight.

After an extended day of mountaineering, I’m often eager to toss off my sneakers and rapidly get into my sandals, however the RocFly had been so comfy that I used to be comfortable to maintain them on whereas organising my tent and doing camp chores.

All Terrain Sole

I typically get pleasure from sporting minimalist sneakers for the flexibility to react and adapt rapidly to the form of the bottom under my ft.

The Adapter-Flex groove helped the shoe mimic the extra versatile soles of minimalist sneakers, permitting the shoe to flex and adapt to extra technical terrain and making steep uphills and rocky trails simpler to navigate. The 4 mm graphene-infused rubber lugs offered stable grip and stability by mud, on moist and trail-worn rocks, over logs and extra.


I did some important bushwhacking in these sneakers and I’m actually impressed at how nicely the RocFly endured the scrapes and pokes from rocks, roots, and branches. The ripstop material and wrap-around protecting bumper had been soiled however in any other case confirmed surprisingly minimal put on after twelve days of exhausting use. One among Inov-8’s objectives is to make extra sturdy and longer-lasting sneakers than the present {industry} common of about 500 miles.

The only additionally showcased the sturdiness of utilizing graphene-enhanced supplies. The lugs had been simply as grippy on the final day as the primary. After over 100 miles of use, there’s little or no apparent put on on the outsole. The one hit to sturdiness was that the upward-wrapping toe outsole on each sneakers partially unglued from the higher material throughout the first few days of wear and tear.

Inov-8 RocFly G 350 GTX Cons

Tapered toe field

The RocFly G 350 sneakers are among the many widest Inov-8 makes. Nonetheless, the tapered toe field of the ladies’s RocFly negates among the advantages of the added width, forcing my toes collectively as a substitute of giving them a extra pure foot form. I ended up sporting a shoe half a measurement bigger than I in all probability ought to have to be able to give my toes a bit more room. Which means that the heel wasn’t as comfortable and I had to make use of the additional eyelet and a extra difficult lacing sample to maintain my foot in place.


As a complete, waterproof sneakers merely don’t have the identical breathability as non-waterproof. As wonderful as Gore-tex is, the added membrane merely can’t shed warmth and moisture as rapidly as common mesh uppers. It undoubtedly took an extended whereas for my sneakers to dry after utterly wetting out. My socks would fairly nicely keep damp all day.

I did come to understand the waterproofing each time I hiked by mud, marsh, meadows, or creeklets. Having the ability to trek proper by wetter terrain saved me numerous vitality in comparison with tip-toeing round it. However on a wet day, a water-resistant path shoe received’t preserve your ft dry as water inevitably creeps in from the highest.


The Gore-tex (GTX) model of the RocFly G 350 is presently unavailable on Inov-8’s US web site. If you happen to dwell within the States and need the additional climate safety, then it seems such as you’ll want to attend.

The RocFly are among the most comfy sneakers I’ve hiked in. The deep Adapter-Flex groove permits my ft to maneuver extra naturally and adapt to the bottom equally to after I’m in a extra minimalist shoe. The Gore-Tex safety was useful at instances, however on the finish of the day, I’d be happier having the extra breathable and quicker-drying non-waterproof model.

The most important draw for me of the RocFly G 350 GTX is its sturdiness. Each the graphene-infused rubber on the only and the ripstop nylon higher present hardly any put on after miles on the punishing trails of the Canadian Rocky Mountains. I plan to check RocFly’s assertion that these sneakers will final tons of of miles longer than different comparable sneakers in the marketplace.
