Love these boots, comfortable, fit really great, for a SMALLER size foot, I wear a size 7 1/2, it was perfect., however, if you have a wide, or really high arch, it is going to be tight, so get a size up.  My foot is slim, it was a good fit, with socks! The sole is really great, got these to travel to Greece, for the walking tours, perfect.  Even around the house, they work really well, comfortable, sturdy, rugged Colorado look, I really like them, and I am hard to please, when it comes to support, comfort, and versibility.  HOWEVER, if you are going to add, more support, it will be difficult, as they are narrow!  I wear them with the zipper up most of the time, but, have left it down, works either way.
