Love my Sharkies! Terribly cute, but beware they do run a bit different in sizing. I would suggest going down a half size since they’re wider around the narrowest part of the foot (I have long, narrow feet). I also ordered them in Gray, but received Black — I loved them enough to keep them, but I really do want the gray, still. As for walking around for awhile, I wouldn’t suggest these for that. They’re more silly, but still comfy; perfect for the pool, beach or lake! 💙🦈💙
