Making its way into the stability running shoe category is the PUMA ForeverRun Nitro, an all-new daily trainer that looks to become a reliable workhorse for runners who need extra support as they log their miles. Rather than using a traditional medial post for stability, the Forever Run utilizes PUMA's innovative Runguide system, which is designed to provide a stable experience without being intrusive. Starting in the midsole, the ForeverRun Nitro is equipped with two layers of supercritical Nitro foam—the bottom layer provides the ideal amount of firmness that helps with stability while the top layer sits nicely underfoot and pairs nicely with the snug wrap and arch support of the insole to provide the comfort you need out on the run. Additionally, there is a firm density rim as part of the midsole that cradles the foot and promotes proper alignment with every stride. The outsole is comprised of PUMA's ultra-reliable and highly popular PUMAGRIP for ultimate traction. The outsole also has a unique "bump out" near the big toe to help with any late stage pronating. The upper also contains several key elements of the Runguide system. The heel of the ForeverRun Nitro contains a TPU clip to support the heel while PWRTAPE is strategically placed around the engineered mesh to provide a sleek yet supportive fit. From top to bottom, the ForeverRun Nitro was built to deliver a smooth a stable ride that almost any runner could enjoy.
