I love all of my Merrell shoes. I have 4 pair of the Encore Breeze in different colors, one being in leather. The inserts sure make the shoe. Before I bought these I was wearing tennis shoes to work, my feet wear out quickly and the heel of my foot starts to hurt a few hours of wearing them. I don't get that with my Merrell's. I can wear them all day without pain. I thought it would be a good idea to have an extra pair of inserts, maybe I will put them in my tennis shoes and be able to wear them longer in a day.
