A breathable mesh upper design allows fresh air to permeate throughout the inner environment of the shoe, allowing warm air to escape; creating a fit that is dryer, cooler and altogether more pleasant for the wearer. Granting the shoe's structural integrity, pliable synthetic overlays seamlessly bonded throughout the forefoot and midfoot allow the shoe to retain its uniformity, without sacrificing flex. This creates an upper that can move and adapt with the foot throughout an increased range of motion, creating a highly comfortable fit. The removable sock liner concealed within the shoe provides a soft, malleable and supportive foot bed, yielding greater comfort and direct support underfoot. Creating a complete and stable fit, the reinforced heel counter locks the heel of the foot in place and reduces the risk of slipping. Keeping the foot secure and in place therefore reducing the possible risk of injury and discomfort. Utilising advanced midsole engineering New Balance have created an innovative foam compound that bears the same responsiveness and consistent durability of other New Balance foams encapsulated within a 30% lighter format. REVlite midsole technology offers a lightweight ride without minimising the overall construction or sacrificing underfoot stability or cushioning. Protecting the shoe from the road a high grade rubber compound has been melded to the outer to create a durable layer of protection and grip. New Balance's Ndurance is incorporated into the high impact zones, ensuring maximum durability and longevity.
