These are light weight, perfect for every day use or hiking where you're not putting in the extra effort pulling the shoes up the hills with you. They required absolutely no "break in". I wore them and walked easily 4km two days ago. Unlike the "pro" series on here I bought in the same order that I've got bandages on the backs of my heels for doing an almost insignificant fraction of that. They fit perfectly. If you've had one size 10 pair of Timberlands you've had them all. The different shades of gray and black suit what I'm wearing a lot lately too.
