I got my black classic tall Uggs in November, and I've been wearing them almost every day since. I wore them last night, and I felt something rubbing against my right heel. I took them off when I got home and I had a blister on my heel, and I felt the inside of the boot, and it felt like the shearling wore down! I could feel the seam, but my left boot isn't like that at all, the shearling is still there. Is this normal? What do I do, can I go to a shoemaker and get it fixed?
