My kids never complained once about their feet. They had Keen sandals like
these and I swear I will buy myself some before our next trip to WDW.
I completely wore out a pair of flip flops within 5 days at WDW. I had worn those flip flops at a local theme park multiple times and thought they'd be fine but all the walking (and maybe hot pavement) at WDW flattened them. I got the Disney rash and my legs & feet were killing me by the end of our trip. I ended up wearing the old
crocs I had brought for DH to wear to the pool. That helped a lot. A lot of people don't like Crocs but I have the Malindi style and I really like them. Crocs.com has a lot of sales.
