When it comes to running, going the extra mile isn??t just a figure of speech. Whether it??s morning exercise, intense training, or head-clearing relaxation, a daily regimen of training miles, combined with ordinary movement throughout the day, demands a lot from a running shoe. With running comfortably for longer in mind, the 880 was built to provide consistent performance for the neutral runner.? The Fresh Foam X 880v12 is modernization that can be seen and felt. A soft foam compound, and dual-layer midsole setup is featured alongside a sleek, jacquard mesh upper featuring strategic zones of support and breathability. This kids' version brings all the 880v12 has to offer to growing feet.
