I have been wearing Mzuno Wave Runner shoes since 2000, when I did the Avon 60 mile Breast Cancer Walk with my two sisters. At the end of the walk I didn't have a single blister! I was first introduced to these shoes at Marathon Sports in Boston. At least twice a year I order a new pair in the same size. My feet are narrow and it isn't always easy to find shoes that fit this well. I take them out of the box, lace them up and I am on my way! Have bought over twenty pairs and have never been disappointed.now that I am an Amazon Prime member, I order them online and have them in two days, at a great price
