Let me start by saying that I have been wearing Mizuno's Wave Rider men's running shoes for 5 years. Every 12 months I go back to Revain and order the latest model, mainly because of the superior cushioning and foot support. Just as I did for the new 22 series a few days ago. What a disappointment.! After wearing them for a few days, I have pain that I have not experienced before. These shoes have a different cushion than previous models, so the Mizuno Wave Rider shoes offer maximum comfort.
