I've finally had some to catch up on threads - just found this. I have these shoes and I love them! The provide nice airflow over your feet. I wear a size 8/8.5 in normal shoes and an 8.5 (40) in running shoes. I wear a size 39 in the PI Vagabonds. The guy at the LBS told me these shoes tend to run a little big (not so fast, though). SK/withm - resist the urge... That seem's to be the case for me.
