Wore these to WLC without having broken them in but that wasn't a problem.  I did get a few blisters but they seemed minimal compared to what I've experienced from GI boots besides my feet weren't at all conditioned and I expected a few foot issues from long road marches.  These babies are light and were a dream doing land nav.  For those who like to do an airborne shuffle or slow jog when doing land nav or when rucking, these are on point.  I usually wear a 7 1/2 but sized up to an 8 based on other reviews and they fit perfectly.
