My favorite shoe for WDW are the OluKai Ohana flip flops. My second choice are the Cobian Braided Leather Bounce (sort of like the old original Teva Mush, but mushier with an even better arch support). I also like the Montrail Molokini and the Orthoheel Tide or Wave. The Sketcher Tone Up flip flops also work for me pretty good down there. Nothing compares to my beloved OluKai Ohana, when my plantar fasciiatis is acting up though.
