Verdict from 8.6 hours of research from the internet

6 reasons to buy

  • That the Mizuno Enigma 4 is a superbly comfortable shoe is a common denominator in many reviews.
  • The 4th version of the enigma runs lighter than its weight indicates, according to several comments.
  • The cushioning is plush.
  • There is a very nice rolling motion through the gait cycle, noted a few runners.
  • Mizuno’s Dynamotion Fit helps hold the foot in place without hindering the runner’s natural movement.
  • A breathable mesh ensures a cool and sweat-free run.

3 reasons not to buy

  • The price point is too much for quite a number of runners.
  • It is a bit stiff for some.
  • The 12mm heel offset lessens the stability of the shoe as observed by a handful.

Bottom line

The Wave Enigma 4 is Mizuno’s answer to a relatively lightweight trainer that can slog through miles of daily running. It has more than enough arch support for long runs with a very smooth transition from landing to take off.

  • Mizuno introduces only a few changes in the 4th edition of the Enigma. The most noticeable change is the removal of the other overlays, relying instead on the Runbird logo to help secure the midfoot.
  • The ankle collar has been lowered just a tad to secure the heel in a very comfortable way. Mizuno made the flex grooves a little bigger and deeper in this version to enhance flexibility.

The Enigma 4 has a fit that is clearly very similar to the previous model. It has a nice wraparound feel in the heel and the midfoot while the forefoot has decent room for the toes to splay. Runners with medium to slightly wider feet should be very comfortable with this kind of fit. Medium to extra wide in the women’s and men’s models are available. The sizing is standard in this shoe


The outsole is a trademark of Mizuno road shoes. Runners should be very familiar with the horseshoe segmented heel that is covered by X10 rubber compound for added traction and durability. Most of the midfoot and forefoot are a blend of a softer rubber and the X10. There are flex grooves in the outsole for better flexibility. This material can also be seen in the Enigma 6 and Rider 22 running shoe.


The iconic Wave, which is made of thermoplastic material, continues to be a major factor in the midsole construction of the Enigma’s 4th version. It is located in the heel and the forefoot. On top of the Wave plates is the U4ic midsole, which is about 30% lighter than Mizuno’s own AP+ foam. The U4ic foam gives the shoe a firm ride and works with the Wave technology to deliver that smooth movement from the heel to the forefoot. Added cushioning in the heel is provided by the SR Touch foam. The breathability of the shoe is excellent because there are ventilation ports in different parts of the sole.


The simplified upper consists of a breathable mesh that guarantees a cool run while the Mizuno logo serves as the main overlay that helps with the midfoot security. The ankle collar has been lowered a bit to hold the heel in place and remains to be very well-padded like the tongue. This upper construction is called the Dynamotion Fit and helps provide an almost sock-like feel.
