New Balance Fresh Foam X 880v14 vs Fresh Foam X 880v15

The New Balance Fresh Foam X 880v15 has had several major updates that make it a very different shoe from the New Balance Fresh Foam X 880v14. The v15 is much taller, sitting 5 mm higher in the heel than the v14. With its less pronounced heel-to-toe drop, the forefoot of the v15 sits 7 mm higher, so there is more cushioning underfoot. New Balance also changed the outsole grip pattern on the v15, leaving a bit more of the foam exposed and fully gusseted the tongue to improve lockdown. Overall, the v15 feels much more like a running shoe, while the v14 is more of a walking shoe.
