I’ve worn several pairs of Reef sandals for more than 10 years now, and they are simply the most solid “flip-flops” I’ve owned. I’ve tried other brands, but they fall apart in stressful conditions or delaminate after a few months of wear. Reef consistently holds up, and I usually wear mine until the rubber is paper thin on the bottom. Right now I’m wearing the “Leather Smoothy” in black – the leather top seems to hold less odor. They have many different styles and colors to choose from for guys, girls, and kids.
