After two summers, my best favorite pair of flip-flops are worn beyond belief. I bought some to replace them, but they are so uncomfortable. I know summer is winding up and flip-flops are hard to find, but many stores mark their summer stuff down around this time of year, so there may still be some out there. Where do you buy cheap, nice flip-flops? Where do you think I could get a decent pair this time of year? Thanks for the help!
