These are very comfortable shoes and I like them feel of them, however I only wore them for about 2 hours after receiving them and the springblades near the middle (arch of the foot) started to rip away from the sole of the shoes, yes not just one of them both shoes, left and right. Unbelievable, I thought they would last at least a day.  I did nothing but go on a short leisurely walk around town. Do not buy
