I tried the new Mizuno Wave 4. This shoe is described as stability shoe with a new midsole material, XPOP which is supposed to have a floating effect. The shoe is high quality. It is stiff from heel to toe but can twist slightly. It felt a bit snug in the width when on the feet. The feel underfoot is firm but well shock absorptive. I did not feel any floating feeling. I was hoping this would be my spring and summer daily trainer but I think the snugness of the shoe might be a problem particularly with the warmer weather on the way.
