The guys over at RunningWarehouse recently posted a sneak peak of the Mizuno Wave Musha 5. Fans of the Musha 4 will be pleased to find the midsole component unchanged and still uses Mizuno’s Wave technology. Mizuno has decided to go with a much more streamlined upper design with this 5th iteration. Stripping away the number of overlays gives users a sock like fit and reduced weight. The Wave Musha 5 weighs in at 7.4 oz, making it almost a full ounce then the previous model. Look for the Mizuno Wave Musha 5 in January 2013 for $90.
