These are great. Attractive, thoughtful design and super well-made (here in Vermont!) from quality materials. They were a big splurge for me but I am glad I did it, it is a joy to have goods you use every day that are made locally and made for the long haul. These are going to be with me for many, many years.
I usually wear a 10.5 or 11 depending on brand and got the 12 per the size chart, this worked out well for me. I would not want to walk miles in them as there is space, but for house shoes it is perfect; they stay on well enough with my usual wool socks and I can get them on with little effort.
