Just received the Carson pull on boots!  I must say they are gorgeous and so well made.

Sizing: I always wear a size 8 but after speaking with a rep at Frye I took their advice and ordered a 7 1/2 and they fit perfect!
Very comfortable although there is a bit of sliding around in the heel area but I think that will resolve with wear.

Color:  I ordered the Smoke because I wanted a gray boot.  I Called the new Frye store in NYC and the salesperson assured me
she had seen the Smoke color and that it was like a gunmetal gray.  Ummmm not really!  They are not gray at all and why the Frye co calls them smoke is beyond me.  They are brown with maybe a twinge of gray if you close your eyes and wish really hard! My husband just came home from work and I asked him the color and he said they are brown! I will say they are a nice shade of a medium brown though so don't order Smoke if you are looking for a pair of gray boots!

So I'm unhappy with the color and will return the Smoke and get another color because the boot itself is really nice.  And yes it does slouch a bit as it is not a stiff leather so it will slide down a some.
