Review on Ultimate Comfort & Lightweight: NORTIV Sandals for Men - Athletic Memory Shoes by Christian Bennett

Cut edges along the valve, down to the toe of the foot, are razor sharp and no "breaking in" or adjustment will mend it. In less than 5 minutes, the right shoe cut my husband's thumb so deeply that blood flowed from the wound. If you are diabetic, DO NOT BUY THIS. You will cause serious injury if the edges of the top flap come into contact with your leg. Too bad I can't return them as they were actually out for 5 minutes. That's a waste of money.
