So it’s quite commonplace now to have a secondary layer of grooves and we call them hydroflow grooves ## Hydroflow Grooves Work Hydroflow grooves filter water away from impact area to maintain spin rates in rain. > Also in wet conditions they will filter water away from the impact area, so you shouldn’t see that drop off in spin ## Groove Design Challenges Mizuno faces R&A rules on groove design, requiring multiple iterations for compliance. > I imagine in terms of making sure that the design is conforming, [it] potentially might take a couple of iterations, just because The R&A are so hot on groove tech these days ## Key takeaway Water between ball and clubface decreases spin on wet days, but Mizuno's hydroflow grooves maintain performance.
