I bought some Ecco Mary Jane style shoes for our upcoming Disney trip. They are so comfortable

. The first time I wore them I went to the mall and walked around about 4 hours. They were very comfortable and I didn't get any blisters at all. They don't feel like they even need to be broken in. I liked the style because it's open and cooler than a gym shoe but more substance and support than a sandal. I liked them so much I bought this pair and a pair in black. The nice thing is that the heel strap is adjustable as well as the strap that goes across the top of your foot so you can create a custom fit with these.
