I never have problems with my feet at home. The normal wear and tear of everyday work and walking never bother me.
However, there is something about Disney (could be all the walking and the heat!) that really gets to my feet. Over the years I have tried walking sneakers, running shoes, and various sandals, and the Nike Straprunners by far have been the best for me.
The velcro strap adjusters allow for a customized fit, and there are no sore spots where the straps meet, which I have found to be a problem for me with the Teva's. The material used on the Straprunners is more comfortable and seems to mold to your foot. Your feet don't sweat as in sneakers, and they are waterproof, so if you go on Kali River Rapids, or get caught in a sudden downpour, your feet are dry in no time.
To look at them you wouldn't think they had enough cushioning to be good walking sandals, but the material they are made with is a good shock absorber I guess, and they are very lightweight.
I know everyone's feet are different, so what works for one, maynot be good for another, but I love my Straprunners, and wouldn't go to WDW without them.
