Day two with the new footwear. Didn't notice it yesterday, but today the internal 'seam' at the rear of the boot (why the hell does it protrude inward?!) chaffed the hell out of my Achilles. Granted, I wasn't wearing my finest boot socks, but this isn't supposed to happen. Before I send them back, got any tips on how I might rectify this problem (short of Moleskin every day)?
