Are they still stiff?
mine are so not comfy...
I wore them out 3 times now, each time I walked a couple of miles in them and they are now very comfy. There is still a little stiffness to them but I am sure it will get better soon. I worried about the size as I sized down (my usual size sold out) but it feels much roomier now than when I tried it on in store.
Before I took them out I wore them with a very think pair of socks at home for a bit, that helped too.
