I loved these when I put them on - but like other reviewers I was a tad concerned about the sizing. I wear a 7.5 or 8 depending on the shoe/boot style.  I got these in an 8. At first I thought they felt too big, but once I got the right socks on they were perfect. I decided to be daring and wear them to work without breaking them in.  Not a problem! I was happy to discover that these were completely comfortable and I wore them all day without any issues. I would much rather wear boots right out of the box than take weeks breaking them in via a smaller size. I'm quite happy with these.
