Mizuno brings club fitting to a new level with the Performance Fitting System. Our patented technology quickly measures the five areas of the player's swing: headspeed, tempo, toe down, kick angle, and release factor. This determines one's "Swing DNA" to recommend the perfect shaft and set makeup for your individual swing. Please note this app is used by Mizuno fitting dealers only, and some features are not available in all countries. Our redesigned app puts even more knowledge at your fingertips: - Refined fitting technology with recommendations better tailored to the player's unique swing - Compare E.I. curves of shafts of any flex or weight showing your personal Bending Profile - 3D Shaft Chart highlights the science behind fittings like never before - Build a full set, including Irons, DLRs, Wedges, and Woods - Simple, intuitive design works well across all platforms
