My heels had been so sore for days I was so active walking , exercise, walking and climbing a lot at job, etc. I knew it mainly reason, not amount of stretching, massaging, or yoga can resolve it. So when I tried walking in them, mind you I am woman supposed having women reef but it not on sale that time as men. So I tried men in smaller size, pray it worked. It did! It also helped easing my injury after short time. Wow! I can understand why,it feels so cloudy to feet. I was gladly wandering in them. It's one of best flip flop I would recommend to anyone with plantar fasciitis, heels injury, or any kind injury. It takes it easy and boost up...takes your feet off floor. Comparing to Spenco women yumi or good arch support, it is almost similar to just take feet off and have feeling of memory foam under feet.
