I bought it in July and haven't worn it for about a month. When I started wearing them MAYBE twice a week for a quick walk or trip to the store. In this SHORT period of not walking much, the sole has WEARED DOWN. The center of the sole on the ball of the foot and heel is worn and cracked except for the white inside, so the sole has no cracks to the inside. Now I can put my finger through the hole. I'm older and I've NEVER been strict about shoes. I mean, I have shoes that I've worn for YEARS…
