Women Superfeet Womens RocFly G 390

Jump to: Our Verdict / Features / Specifications

A light and airy boot, that’s still hardwearing underfoot.

Inov8 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 super-comfortable upper that perfectly balances the need for support, protection and breathability. All this at a weight of just 390g. Prepare for endless adventure.

Our Verdict

Inov8’s Womens RocFly G 390 are based on a trail runner, for those who like a robust bouncy sole. Not as stripped down as some Inov8 trail runners, these boots are more of an all-terrain do anything, go-anywhere shoe. Equally good at road walking as it is on rocky terrain, if you’re not sure what’s going to be underfoot, this is the boot for you.

The “Graphene Grip” rubber really is incredibly robust, paired with the “G-Fly” foam and you have a strong and grippy sole that’s adaptable to the trail, and still provides a lot of cushioning

The Rocfly 390 is not waterproof which may be a deal-breaker for you. If not, when these boots will get wet they will dry incredibly quickly. This also means on hot days your feet are able to breathe amazingly well, and vent moisture easily, something that Gore-Tex boots often struggle with.  

I don’t think I’ve yet come across a shoe I can comfortably wear as long as these, 10 hours of walking, over a variety of terrains and my feet still felt fresh.

Features

Outsole

• GRAPHENE-GRIP™ rubber delivers the world’s toughest grip – insane sticky traction AND increased durability, no compromise. 50% stronger, 50% more elastic, 50% harder wearing – all extending the life of the outsole. 
• 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 and rubber dimples give extra grip on slick surfaces. 
• Vertical grooves cut into the rubber allow the foot’s metatarsal bones to move more independently, aiding adaptability and flexible grip when hiking over uneven terrain

Midsole

• Graphene-enhanced G-FLY™ foam is less resistant to wear, and so retains its optimum levels of cushioned thickness and snappy energy return for longer, helping long-distance thru-hikers and adventurers feel fresher over greater distances.
• 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.
• Stack heights of 30mm in the heel and 24mm in the forefoot, help make this our most cushioned boot ever. A 6mm drop hits the sweet spot for long-distance comfort.
• A 10mm deep ADAPTER-FLEX™ groove allows the boot to adapt, react and mould to uneven terrain for a responsive, agile feel that is free of rigidity but full of cushioning. It is positioned to work in tandem with the foot’s midtarsal joint to increase flex and mobility.

Upper

• Flexible fit of the knitted upper adjusts to the natural swelling of the foot when hiking long distances. Lightweight, breathable and quick drying, this super-comfortable boot is designed to go all day, every day. 
• Extra durable overlays protect hard wearing zones against debris and vegetation.
• Lacing system has been specifically designed for fluid lace movement when putting the boot on or taking it off. The top speed hooks on either side include grooves that grip the laces when tied, aiding a secure hold. 
• Wide toe-box, plush tongue and padded collar all enhance the overall hike comfort, while a double-layered toe guard increases protection against rocky terrain.
