These boots are awesome!  I wear custom made orthotics and worried that the boots might not accommodate them.  I couldn't order a size larger, because I wear an 11 and that's as large as these seem to run.  My orthotics fit in them snuggly and comfortably.  I was able to adjust the buckles so that the boots were comfortable.  These boots were surprisingly comfortable the first time I put them on!
I love love love them!
