Womens RocFly G 390 GTX

Jump to: Our Verdict / Features / Specifications

Hillwalkers, day hikers and thru-hikers will all love this hybrid boot/trail runner combination. They are lightweight, hardwearing, any terrain walking boots that use Inov-8’s durable Graphene-enhanced G-GRIP.

Inov-8 says: 

A revolutionary boot like no other, the ROCFLY™ G 390 uses a unique Graphene-infused G-FLY™ foam that supercharges your feet so you can hike further than ever before. The world-first foam is scientifically proven to deliver 25% greater energy return and retain its optimum levels of underfoot rebound and cushioning for longer, thanks to the infusion of the planet’s strongest wonder material. The boot also features a pioneering ADAPTER-FLEX™ groove that allows it to adapt and react to the terrain with the type of agility usually reserved for trail running shoes, GRAPHENE-GRIP™ rubber that ensures the world’s toughest traction over all types of ground, and a quick-drying upper that perfectly balances the need for comfort, protection and breathability. All this at a weight of just 390g. Prepare for endless adventure.

Our Verdict

Inov-8 make fantastic trail running shoes and hiking boots, so I was very excited when they combined both into this lightweight hybrid.

As soon as you get these on, you can instantly tell how comfortable and well-cushioned they are. They support the ankle but are so light you feel like you have slippers on. Out-of-the-box comfort!

Inov-8’s biggest draw for me is their durability; Graphene infused rubber on the soul of their shoes, G-GRIP seems far more rugged than any rubber used by anyone else on the market. They have deep 4mm lugs that aggressively grip the dirt on any terrain.

They have a well-cushioned midsole that provides a good amount of bounce; these boots propel me forward. The biggest test for me is always how badly my feet hurt after a long section of road walking on a multi-day hike, and these kept me going without being in too much pain. Big fan of these and Inov-8 in general

Features

• World’s toughest grip: Graphene is the world’s strongest material. Graphene-enhanced G-GRIP rubber delivers insane sticky traction AND increased durability, no compromise. 50% stronger, 50% more elastic, 50% harder wearing.
• Superior traction: 35 multi-directional 4mm deep lugs on each shoe have been meticulously shaped and positioned to improve both propulsion at the front and braking at the rear. Measured spacing between the lugs prevents debris from sticking to the outsole, while water dispersion channels give extra grip on slick surfaces.
• Feel flexible: Vertical grooves cut into the rubber allow the foot’s metatarsal bones to move more independently, aiding adaptability and flexible grip when running over uneven terrain.
• Take flight: Graphene-enhanced G-FLY cushioned foam is more resistant to wear. It retains its thickness and optimum levels of snappy energy return for longer, helping runners feel faster and fresher over greater distances.
• Go the distance: The foam gives 25% more energy return. Laboratory tests show that even when the foam is aged to mimic extensive use, it still delivers more energy return than some unaged foams. Athletes testing the foam said it was still performing well after 1,200km – double the industry standard.
• Best in protection: GORE-TEX product technology delivers the ultimate in waterproof protection and 365-day climate comfort. The upper material – a lightweight ripstop nylon – delivers excellent protection and long-lasting durability as the big miles stack up. The gusseted tongue keeps debris out of the shoe and a front bumper protects the toes.
• Adapt and react: A revolutionary 10mm deep ADAPTER-FLEX groove makes this the only max cushioned boot that adapts, reacts and moulds to uneven terrain for a responsive ride. It frees the stacked midsole of rigidity and works in tandem with the foot’s midtarsal joint to increase flex and mobility.
