very comfortable right out of the box--except...im used to 'fishermans'-type sandals so this strap that goes over my toes are taking a little getting used to.  fit is spot-on & even tho i wondered how comfortable the footbed would be, not to worry.  im still getting used to living here in Palm Strings CA moved from the mountians & high desert of central Arizona & thus no lakes or streams for me to hike thru but even the 1 time i walked thru water, they were no-slip.<br />i would buy them again
