Just got these and they are seriously the most comfortable flip flop I've ever worn. They are sized perfectly over the top, they keep you in but aren't too tight. The yoga mat part was a bit smelly out of the box but then wore off pretty quickly. The bottoms are a little slippery on hard floors but not too bad. I also love that they don't leak color on my foot like my reef squishy's. Though it's too be seen if they end up packing down after some wear, they seem pretty durable. Will be a sandal that I'll wear most of the summer!
