I'm late 50's and my feet our my babies and I then to like them to be happy. Needless to say, after 38 some trips, my feet seem to like a pair of 99 cent flip flops bought years ago and to switch of, a pair of Route 66 K-mart suede slip ons. We live our life 8-10 hours a day in work shoes and we're always happy and comfortable, if you're not used to wearing tennis shoes or the like, don't try to blow your bucks on a expensive pair and think you'll be happy in WDW. Your feet are you friends, what they like and want is what fits them to a tee for an eight hour period. Throw in some Florida heat, sweat and constant walking and they better be happy or they will rebel. When they are tired, we relax them, we rub Absorbine Jr. on them after a shower at night and take multiple breaks during the day. Happy feet are a blessing in WDW, treat them kindly.
