BEAUTIFUL boots! I wear an 8 and bought 7 as everyone says they run large. Good suggestion. This is a quality boot thats drawn many complements. They are very comfortable for an all day wear.
UPDATE:  After wearing my adorable boots a few times the pin that holds the strap in place pulled through the rubber tab.  Nothing tore, so I took that to my shoe repairman who put a bigger fastening screw so the pin cant pull through.  MY RECOMMENDATION: Buy the tall Joules with the regular buckle on the side or back.  The adjusta-strap could be a problem.
