"I have bone spurs and plantar fasciitis, so I have to be pretty picky about what I wear in terms of comfort. I needed some flip flop type sandals, and based on reviews that these were pretty comfortable, I took a chance. They have great arch support, and the criss-cross straps help support the foot side to side. The thicker sole is extra cushioning. They are very comfortable, and I'd definitely buy them again."
