On a lark I bought the hot pink patent leather 8 eye Martens. I was surprised by how comfortable they were straight out of the box. I usually wear a US 6.5 women's shoe and the U.K. Size 4 is a perfect fit. I could wear a thicker sock with them if I choose to do so. I love this blue color; it is vivid and bright; great with denim, black velvet leggings, what ever you like. I wore them to the Air and Space museum right out of the box and did not have sore or tired feet. The sole on this boot is incredibly comfortable. Highly recommend.
