Shoe Fit Scale: 1-5 where 1 represents inov-8's closest, most narrow fit and 5 has the widest fitting toe box. The lower the number (the narrower the fit), the more minimal internal movement of your foot when running fast on technical terrain. The higher the number the more the shoe fits wider feet and those wanting extra comfort in the toe box - perfect for longer runs and races when toes begin to swell.

inov-8 Notes:
For technical footwear the correct fit is essential for comfort while running.
As a guide finding the right fit for you, stand upright on a ruler whilst wearing the socks you run in and measure from heel to toe. Find the nearest figure in the 'in cm' column and read from the relative figures in that row.
This is a guide only to choosing your initial shoe size and a 3mm footbed or vclume adjuster may be inserted to fine tune the fit.
The revolutionary Rocfly G 390 is a lightweight boot for light, fast hiking adventures and features a graphene-infused G-FLY™ foam midsole, a wonder foam that supercharges your feet all day with a scientifically-proven 25% great energy return and an ability to retain optimum levels of underfoot rebound and cushioning for longer. Other features include an ADAPTER-FLEX™ groove to adapt and react to terrain the way trail-running shoes do, a GRAPHENE-GRIP™ outsole for the toughest traction on any terrain and a super-comfortable upper that balances support, protection and breathability brilliantly.

G-FLY™ foam: Graphene-enhanced G-FLY™ foam retains its optimum levels of cushioned thickness and snappy energy return for longer, helping long-distance hikers fell fresher over longer distances.
Graphene: is a sheet of carbon just one atom thick and is the strongest material on earth, 200 times stronger than steel, as well as the thinnest. Graphene is extraordinarily flexible and can be bent, twisted, folded and stretched without damage and is almost entirely transparent. Infused into rubber in the inov-8 G-Series of shoes has proven to make them 50% stronger, 50% more elastic and 50% harder wearing. This graphene-enhanced rubber can flex and grip to all surfaces more effectively without wearing down quickly to provide a reliably strong, long-lasting grip.
