Guess I'm the lone dissenter about Keens. I got the Venice style and tried to break them in before my WDW trip, so I hotfooted around Manhattan in them. OMG, were they ever the most uncomfortable shoe disguised as a walking shoe. I had the right size, so that wasn't it, but I had hotspots that required two layers of moleskin just to make them tolerable. They rubbed on the heel, and on the outer part of my ankles (below the bone) on the sides. The balls of my feet also felt like they were on fire.
I literally cringed the second day at the thought of slipping my sore feet gingerly into those painful shoes! Later, I heard a lot of mixed feedback about the Venice style of Keens. Looking back on it, maybe that's why I found so many websites clearancing them. Lucky for me, I contacted the website where I got them and they agreed to let me return them.
Crocs and Teva Mush flip flops were my shoes of choice last week at Disney, and I never had a single problem with sore feet. Just my $0.02 worth!
