Got a pair of used cordovan dress boots from another member here, and I really love the construction of his boots. Anyway I've been wearing them for about 4-5 times and I started to notice there is something hard on the left insole, right behind the ball of my foot. It's not extremely uncomfortable, but it feels more like stepping on small pebbles. So I got home today, and put my hand inside the left boot, and indeed found a raised spot. It feels like a very hard, almost like an extra piece of leather was inserted in that area. Anyone ever has that problem?
