Swing full speed with Mizuno Enerzy – our softest and bounciest midsole and insole. Fresh from a 2020 introduction to Mizuno’s running shoe line, Mizuno Enerzy is 17% softer and delivers 15% more energy return than any prior midsole material, the insole is 20% softer delivering 28% more return. This gives Mizuno Enerzy the dual impact of intensifying ground forces for enhanced clubhead speed and reducing walk fatigue. This combines with our spikeless Wgrip technology, delivering a 33% increase in grip production vs the X10 rubber compound featured in previous models, to offer exceptional performance. In Full Grain Leather with integrated tongue and Boa closure system for a slip free, snug fit.
