text: Got these yesterday and had to send them back. My baby toes kept sliding out of one of the openings, so I know that would have soon lead to discomfort. I found them to be a little bit large length-wise, and certainly could not have worn half a size larger as some reviewers have recommended. I have wide feet, and they were okay in that respect. These cannot be adjusted in the heel, so I found that my foot kept sliding back which probably accounted for the reason that my little toes were poking out.  I found a pair of Keen Whisper sandals that fit oh so much better and have a bit more support than the Clearwater CNX.
