Hi, as far as sandals in the parks go, I would recommend Born, Clarks, or Keen. The Keen are kind of a cross between sandals and gym shoes - they are also available in amphibious models. The Keen aren't as cute as some others, but they are very comfy.
I buy all my shoes at Zappos.com now. They have free shipping,(very fast - sometimes overnight), no tax, and free shipping returns.
I have actually worn a pair of Skechers sandals around WDW. They were comfy for me - very cushy. But overall, I really do find the more expensive brands are better shoes. You do kind of get what you pay for. Look for the good brands on sale.
Just make sure the shoes are comfy from the start. If they need to be broken in, they aren't right for you and will wind up rubbing you wrong after extended wear. I would invest in a really good pair because you will be on your feet a lot during a WDW vacation. If my feet are achy, it makes me feel cranky.
Good luck & happy shopping!
