Brooks Ravenna 8 Running Shoes With stability and support in mind, the Brooks Ravenna 8 ensures you clock up the miles with comfort and with confidence. Air Mesh Upper The upper of the Brooks Ravenna 8 has been constructed using Air Mesh which keeps the feet cool and dry. Air Mesh works by actively and efficiently wicking away the build-up of excess sweat and moisture to leave your feet cool, dry and comfortable as you strive for the best results and performance. Additionally, cool air is encouraged to circulate, creating a drier, healthier environment for your feet to thrive. Synthetic overlays have been strategically placed across the upper for protection and resistance against abrasion as well as friction. A padded tongue sits comfortably against the skin and guards against irritation such as chafing while the traditional lacing system offers a secure, locked-in feel while you run. The 3D Fit Print adds stretch for a full range of motion without restricting your feet, giving you the freedom to move. BiaMoGo DNA Midsole The BioMoGo DNA is a cushioning technology that is soft and comfortable. It carries the footwell and even moulds itself to the shape of the underfoot, allowing the platform to fully support the curvature of the underfoot. Having the cushioning and support helps to lessen the impact placed upon your joints as well as attenuating shock, minimising the potential risk of injury or discomfort. The midfoot transition zone is designed to propel your movements from the heel to the toe, to maintain the most efficient gait possible. Ideal for runners with slight to moderate overpronation. Blown Rubber Outsole The outsole is made from a blown rubber compound which is superbly durable and will allow the shoe and foot to be protected from possibly loose and dangerous debris that can often be found on the ground. Having optimal grip and traction will allow the wearer to run with confidence knowing they have a shoe they can truly rely upon.
