The other reviewers said that this product fit like a glove with minimal breaking in needed and they were right!  I haven't worn boots in years and my feet were ready to hurt after 9 hours of walking over coarse rocks, boulders, uneven terrain and 4+ inch nail-like thorns.  I got home and my feet were great!  My calves were a little sore but my feet were fabulous as were my ankles!  Slip resistance exceeded my expectations and where many other boots have been punctured by thorns - mine didn't have a scratch.
