I have never worn the LL Bean type but last year I wore these Ecco Mary Janes....
They were very comfortable. I would suggest using Body Glide if you wear them without socks. I do not wear mine with socks. I go barefoot. They are nice because when they get wet, they dry quickly and with the velcro closures, you can make a custom fit.
I bought the LL Bean version at the end of last summer at a super price with a coupon. I wore them a couple of times and loved them! The only problem was the color...the only pair in my size was green.
I have them and thought they would be perfect for wdw but the soles are really hard and don't bend with your feet. I ended up having a tendonitis issue in my big toe when I wore these at US/fl. I prefer Teva mush flip flops.
I wear cross trainers made by RYKA that I purchase at the Woman's Foot Locker. These shoes are fabulous and my feet never feel fatigued at all. A little pricey but well worth it.
