Inov8 Roclite Ultra G 320 Trail Running Shoes Inov8's first Roclite shoe to feature Graphene in both the rubber outsole and foam midsole gives all-terrain grip for longer runs and adventures when extra cushioning is desired. Inov8 Shoe Fit Scale For technical footwear, a good fit is essential to enhance your performance. Inov8's new Shoe Fit Scale makes it easier to find the perfect fitting shoe. All Inov8 shoes are designed with Met-Cradle technology to lock down the mid-foot for a stable hold, where they differ is in the toe box. The shoes are now graded from 1 to 5, Grade 1 representing their closest, most precise fit and Grade 5 representing the widest fitting toe box. The lower the number on the scale, the narrower the fit, which ensures minimal internal movement of the foot when running fast on technical terrain. Shoes with the higher numbers on the scale will suit athletes with a wider foot and those wanting that extra comfort in the toe box. This wider toe box allows the toes to splay for increased stability when lifting heavy weights. It's also perfect for longer runs and races when toes begin to swell. Inov8 have graded the Roclite Ultra G 320 Trail Running Shoes as Grade 3. Durable Mesh Upper The upper of the Roclite Ultra G 320 from Inov8 has been constructed using a new super-tough mesh upper material that delivers greater durability to help extend the overall lifespan of the shoe whilst remaining highly breathable. Boasting both durability and breathability, this hard-wearing mesh offers superb protection and long-lasting wear whilst allowing cool air to permeate the fabric and remove uncomfortable heat build-up, creating a healthy environment that your feet can thrive in whilst preventing dirt and debris from entering the shoe and causing discomfort. A reinforced front-end bumper further protects the toes from sharp debris and Inov8's ADAPTER-FIT technology forms a supportive cradle between the heel and arch. This technology has been teamed with the laces to ensure a locked-in feel and increased stability, perfect for runs over rough terrain. G-FLY Graphene Foam Midsole The Roclite Ultra G 320 features Inov's Graphene-enhanced foam G-FLY in the midsole construction. This will provide you with the ultimate comfort and response that can be felt mile after mile. The foam delivers 25% greater energy return, which is guaranteed to provide you with a spring in your step. This will help push you further and faster than ever before. It will also retain its optimum levels of underfoot rebound and comfort for longer, allowing you to run faster and feel fresher. Inov's G-FLY Graphene foam has also been coupled with a higher stack height to deliver more underfoot cushioning and energy return with each and every stride. A BOOMERANG footbed further enhances the bouncy feel provided by the midsole. The effective cushioning of the midsole will mean that joints like the knees and ankles will have reduced impact, preventing injuries and fatigue from occurring. Shocks are also absorbed instantly and effectively, reducing the risk of injuries from heavy or sharp impacts against the sole of the foot. Completing the midsole is a flexible rock plate that helps to protect the underfoot from sharp debris below. G-Grip Rubber Outsole Featuring Inov8's G-Grip, the graphene grip rubber outsole provides unrivalled grip and traction over unpredictable surfaces, whilst increasing the outsole durability across a variety of terrain, from mud to wet mountain rock and hard-packed trials, the Roclite G 320 has you covered. Equally happy on or off the trail, versatile 6mm Graphene-enhanced lugs bit and hold across all ground, from hard rock to soft bog. Thanks to the world's strongest material, Graphene, featuring on these deep lugs, the Roclite G 320 provides you with longer-lasting tough grip over all terrains.
