I have plantar fasciitus, (heel spurs) so it was very uncomfortable for me to walk a lot. I had heard about Ecco being a very comfortable brand, and made the guess to get these for my vacation.  This was my first pair of Eccos, and I used them on a 4 day trip to DC, where I walked nearly all day long, every day so I could see all the Smithsonian museums and do a lot of sightseeing. PS: the Smithsonian Indian museum has a Mitsitam cafe with the best food ever, the bread pudding and squash and trout were amazing.  Anyway, these have been the most comfortable sandals I've ever owned, heel spurs and all, they allowed me to walk 4 days in a row all over DC.  I have ever since worn them even as much as possible, even find myself sneaking them on in a fancy office environment, I don't want to take them off.  Super, super sandals.  Thanks for having these!
