I was at an AE store last week and they strongly recommended going one higher width with the Dalton, due to the way the boot has to be crafted.. E.g., I'm 10D in PA and Strand and they recommended 10 E for Strand. I tried on Dalton in both 10D and 10E. 10D was tighter over my arch-toes region than my PAs and Strands while the 10E was just a little big throughout. Medium socks, instead of the very thin I was wearing, would probably have made the 10E right. Anyone else think this is best - up one notch in width from right size on a 5 last to fit the Dalton?
