I've done it a bunch of times at WDW. You will see a bunch of other people doing it too. No one is going to laugh at you. It's all about preserving your feet for all that walking at WDW! Now if you want to keep your feet happy, but really don't want to wear athletic shoes, you might want to take a look at Bernie Mevs. I'm not really an athletic shoes girl. I only wear them to work out, and at WDW. Last summer I discovered Bernie Mevs (I like the comfi). They are the most comfortable walking shoe I've ever owned. They run a little small. I have a wider foot and I go up a size in them. I wore them in the parks from open to close two months ago, and my feet weren't even tired at the end of the day. I will note that you need to wear them around a little bit for a day before using them for an all day excursion because the first day you wear them the strap will be a little tight after awhile. By the second day, it will have stretched and molded to your foot and will feel great. We only have one store that carries them around here, and the manager told me that they quickly became their best selling shoes ever and that they have to constantly restock to the point where at that time they were getting shipments of them once a week. My athletic shoes are now relegated to working out. No more athletic shoes and socks with capris at WDW for me!
