Not so ugly anymore! Some of the newest styles are pretty snazzy -- mine are navy with a lime green blaze/lightning bolt -- sold as "discontinued" - bought at Sierra Trading Post website for $29.99 - special free shipping code. Wore them everyday for 10 days in August at WDW - no blisters, no achy feet. Received many compliments and questions on where to buy. I personally would not wear them in the shower only because I found that they attract dirt when wet and I want to keep mine pristine. Having said that, I accidently wore them while gardening recently and was able to get them clean with a hard scrubbing with Dawn dishwashing liquid.
I have a special pair of non-thong style flipflops I use for the shower (hate that thing between my toes!)
