Version 4 of the 1260 combines moderate stability with fantastic cushioning. The supportive medial post is molded independent of the rest of the midsole, then applied post-molding process. The result is a more consistent density in both the midsole and the medial post, offering more reliable support and a smoother ride.Other changes in this update include a move to a slightly softer upper mesh for a more plush feel, as well as the use of a more oblique toe shape, which should provide a better fit. Aesthetics-wise, the 1260 v4 takes on a faster look, thanks to an increased toe-spring and the usage of louder colors. Those looking to address their moderate to severe overpronation yet wish to stray away from a bulkier-looking shoe should definitely take notice.
