The Wave Goodbye is the slightly faster twin of the more expensive Wave Phantom
. While it weighs virtually the same, its firmer and more responsive, and it has less midfoot support, which makes for a more natural, if less stable ride. If you have any problems with a heavy or slightly unstable footstrike, the better-cushioned, more stable Phantom is your better bet, but the Wave Goodbye is a great no-frills option. Mizuno has added more support in the upper over last years version, and says the shoe is built on a new last, but our weartesters noticed little difference.
