A quick and nimble lightweight racing shoe, the versatile Mizuno Wave Ronin 4 features minimal cushioning and a semi-firm ride.



The Mizuno Wave Ronin 4: quick, light, awesome. Slip these shoes on and you'll understand what we mean. These super flexible racers are built for speed, with a lightly padded midsole that forms to your foot, bending at toe off and snapping back into place with plenty of energy. The soft breathable upper has a slipper-like fit that caresses your foot as you fly down the road.

  • Mizuno Wave consists of an elastic, thermal plastic wave running from the heel to the midfoot, creating an incredibly springy and well-cushioned ride.
  • AP+ is Mizuno's top of the line full length midsole copolymer material for a lighter, more resilient ride.
  • Smooth Ride is a gender specific network of grooves that minimizes the rapid acceleration and deceleration of the foot to create a smooth heel to toe ride.
  • AIRmesh covers the entire upper and provides breathability to keep the foot cool.
  • Standard Sockliner provides underfoot comfort.
  • Dynamotion Fit creates optimal fit with stretch material in the forefoot and a collar construction that prevents the heel collar from buckling under load.
  • Slip Last involves wrapping and stitching the upper in a bootie-like shape before attaching the upper to the midsole which helps promote flexibility and decreases weight.
  • Flex Controllers placed in high flex areas on the outsole act as miniature wave plates for increased flexibility and reduced weight.
  • X10 located in the heel and forefoot is made of durable carbon rubber for enhanced traction.
  • G3 Sole is a lightweight rubber dot pattern in the forefoot for increased grip and flexibility.

Customer Reviews

Comments: I just bought the Ronin 4 after loving my Mizuno Precisions. I am hoping to use the Ronin for speedwork and save my Precisions for the longer stuff. I feel like the Ronin has a generous toebox and heel cup. I did go up 1/2 size as suggested and think it was a good choice. Not a ton of forefoot cushion but, great shoes for speedy short runs!
