Selket, you aren't alone. I love my Beaches & Niles at home. But, my Niles gave me my first & only WDW Blister in 14 trips. I wear them for hours at home, I don't understand why it happened. But since it did, I only wear my Beaches with socks for short bursts at WDW now. I'm sticking to my Tevas, Clarks & Danskos.
