A performance road racing shoe with a touch of overpronation support, the Mizuno Wave Musha 4 offers minimal cushioning and a semi-firm ride.



The Musha 4 delivers even greater performance with an updated midsole and snazzy new upper. Its minimal yet stable ride receives extra bounce with the addition of an Ap+ midsole for responsive cushioning, and soft overlays provide a more supportive fit that stays comfortable for miles on end.

The Wave Musha 4 is a minimum feature, minimum support shoe designed for racing. It is built with a curved shape.


  • 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 copolymer midsole 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.
  • X10 located in the heel and forefoot is made of durable carbon rubber for enhanced traction.

Customer Reviews


Comments: This review is simply based on a short trial period - I returned them in favor of the Saucony Fastwitch. Fit seemed good, but I didn't like the sole feel. Due to the thin forefoot sole, I would feel where the waveplate ended, which was just behind the ball of my foot. There is a definite change in the support of the shoe where the wave plate ends, which was too noticeable for me. I felt that if it was annoying after trying them on and wearing them for 10 minutes, it would be unbearable after mile 20 of a marathon.

Comments: I'm 16, I run about 50 miles a week, and my 5k pr is 1755. I'm 135 lbs. I've put 900 miles on my 4's. they are by far my favorite trainer yet. Besides two holes on each shoe where my pinky toes rub the shoes are in great condition. I midfoot strike so there is a groove worn into the forefoot but they are just more flexible now. Favorite shoe and would def recommend.

Comments: I've ran 19 marathons with the fastest being 2:36. My weekly mileage now is 60 and I have a normal arch. This is the first time I've tried any model of the Mizuno Musha.  The 4's I liked so far. I did a 11 mile run this morning to break them in and they have great toe box room and true to size.  I like the light feel and yet you could feel the structured support under your foot. They seem to help not to heel strike which I'm a major heel striker so this was a benefit.  I liked the tight rebound off the ground and not a spongy bounce giving you more of a faster stride rate.  I would definitely try these out on a 20 miler.  I believe these could be a definite marathon shoe with the stability that I felt.
