I just found a pair of Skechers Tone-ups at Shoe Department Encore for just $12.97. They are the slide type, not the flip flops.
I decided that I would rather have the flip flop type and found them at Rack Room for $29.99 and then got my son a pair of athletic shoes for 1/2 price with the BOGO.
Has anyone had good luck wearing these at Disney? I have plantar fac. and tendonitis and have to have something to take to the beach and Disney. If we go in the winter, I can wear my Dansko, but in the spring, they would not look cute with capris.
I used the "fit-flops" and the toning sneakers, and still found my feet were killing me by the end of the day. Both at Disney and spending time in NYC.
Seriously, seriously, seriously: the best thing I EVER did for my plantar fasciitis was to make the switch to "barefoot" shoes. For years (I developed P.F. about 6 years ago) I tried to cure it with orthotic inserts, thick shoes (Reebok ZigTechs, "toning" shoes). My feet have never felt as good as they have in the two months or so since I switched.
It takes some getting used to, and I spent about $150 on new shoes (a pair of Vibrams and a pair of Nike Frees), but it is so worth it. I just moved to the city (D.C.) and literally walk around all day (just started going for pain-free runs too!) with NONE of that awful, ripping pain of P.F. Sometimes my feet will be sore at the end of the day just from merit of standing on them all day, but from what I understand eventually my feet will pad themselves and that will go away too.
Another effect, I have a bad ankle and always used to "roll" out (ouch!) on those thick-soled sneakers, it's pretty hard to do that when your feet are hugging the ground.
It's not for everybody, but I just wanted to share because it has literally changed my life and I am THRILLED not to be in pain. I know there are a lot of people who preach going COMPLETELY barefoot, as a young professional that wasn't going to happen for me, but I get a ton of positive effects from wearing minimalist shoes and going barefoot around the apartment.

There's some starter information
