I wore mine for the first time today and I'm horrified! They are KILLING the back of my heel/ankle. It's stiffer in that area than it is anywhere else, and there's a weird horizontal seam on the inside that doesn't help. I didn't notice this at all when I wore them around the house and it's not something I usually have a problem with, but it's rubbing badly in that area. I am wearing socks and leans but it's still a problem. Have either of you noticed this or is it just me? I'm going to have to return them to Nordies if this isn't resolved. It's heinously painful.
