I have these and they are very comfortable. I am wearing them as much as possible before we go to make sure they are broken in. I had a pair of the leather Teva's that were really comfortable, but we went to Universal one spring and I had not worn them all winter and by the end of the day I was miserable from blisters on my heels. I have not had any discomfort from the new sandals, I have had them about a month.

) shopping marathon. I wore them for purpose of seeing if they would be comfortable all day, and they were. I'll be taking both pair with me next week to WDW. 
Wore them to do a bit of shopping and I gotta say they will NOT cut it a full day at the parks, IMHO. The Teva Terradactyls (I know that isn't spelled right!) that I got 8 years ago were a lot more comfy. I may wear them at AK, where we are typically out early, but I doubt they keep my feet happy for a day at Epcot, where we typically stay from open to close.
