The Mizuno Wave Horizon is a max-comfort stability training shoe that has undergone significant changes in its design in recent versions. Originally, Mizuno's Waveplate didn't win fans with its stiffness, but changes to the model by bringing in the Enerzy midsole have improved its competitiveness with other comfortable stability trainers, and the Wave Horizon 6 unveiled a new upper that has put the model into serious competition with other comfort-oriented stability trainers.
