I have no experience except Gator has a pair of the sandals. My mom has the sandals and loves them for regular wear in the summer and also for kayaking and stuff
I know nothing about them for babes, but my mom loves them for every day shoes for her. They seem to run true-to-size. We have a pair of their "water shoes" from our honeymoon too.
Re: Keen shoes
A had a pair of the velcro sandals this past summer. I really liked them, they are constructed well and ran pretty true to size.
I just saw them on Zulily and am debating getting a pair for this summer, I just do't know what size to get
