At the parks? I just got back from our vacation and wore a very old pair of Columbia sandals. They were OK, but I noticed a lot of people wearing the Keen's. I am looking for the open back (with just the one strap across the back of the ankle). I am usually a size 6 and could probably get away with buying a kids size. Also, any recommendations on where to purchase at a good price? Thanks!

They shipped last night and I can't wait to get them. We are going to Disney Thanksgiving week and I hope I have them broken in by the time we leave.
