Mizuno Wave Ronin 4

This is Mizuno Wave Ronin 4 and the Mizuno Ronin series has always been looked upon as aggressive looking road racing flats. The Ronin 4 is no exception. I'm not going elaborate too much about the technicalities of this pair of shoe, but let me start by saying that this baby can really kick butt.

Living up to it's intimidating look and reputation, the Ronin 4  is really a comfortable and light weight (weighs in at 7.0 oz for a men's size 9).  However, as a sock-less runner, I find the wide heel cup of the Ronin 4 a bit annoying, but it should be OK if you are wearing socks. I corrected that by tightening up the laces.

Design for speed-work training or racing, you will notice that Ronin 4 is built with a semi-curve shape.

Cushioning system is based on Mizuno Wave which consists of an elastic, thermal plastic wave running from the heel to the midfoot, creating an incredibly springy and well-cushioned ride. I found that the Ronin 4 is a highly responsive shoe despite it's firm cushioning, making it an excellent pair of racer for long distance races. When you put it on, this very minimal firm cushioning makes you feel fast. No superfluous cushioning to slow you down. But yet, when you pick up on speed you can feel the comfortable ride, absorbing every hard landing you take. Nevertheless, I think this shoe is good for any types of races from 5K to a full marathon.

Flex controllers are placed in high flex areas on the outsole to act as miniature wave plates to increase flexibility and reduce weight. And at the heel and forefoot area, the material is actually made from durable carbon rubber for enhanced traction. I find the grip on wet road is really amazing.

Who wears the Ronin 4?  Franklin Chepkwony of Kenya on winning the Zurich Marathon 2012 (Switzerland) in a time of 2:10:57. Franklin wears the Wave Ronin 4 racing flats. And now me! :)
