Superfeet Outside 2 Sandals were my first expensive high-end sandals. I got it before the summer and wore it for a couple of months. I feel little a bit of strange at first because the sandal has a heel to toe drop and support your feet, but it makes you feel really comfortable. It allows your legs in good alignment and relieves the knees, I feel it help me to recover from my training and racing fast. The build quality is superb, durable and easy to take care. This is my go-to sandal during the summer and also become great feet relax tool after a hard race. Highly recommended
