Purchased 'Sheila' clogs in pebbled copper, and loved them so much that I also ordered them in black.  I wear either the black or brown every day, and have 'Tambour' in black with the patent leather detail for a dressier look.  Comfortable & well-made.  I had no problems with one being bigger than the other, as some reviewers have mentioned.  Perhaps that was a previous problem which has now been solved.  Also, I've had no problem with tripping or falling, as some have had, but I grew up wearing clogs so I'm used to them.  If someone does have that problem, one reviewer at the Ariat site has a good suggestion for you.  I wear 6 1/2 or 7 in most shoes, and Ariat clogs in 6 1/2 are a good fit for me with a thin sock.  (I have a narrow foot with high arch)  I do use a shoe horn when putting them on, so as to not distort the opening at the heel area.  If you like clogs, I recommend Ariat, hands down!
