I found a pair of Ariats quite by accident two years ago and have since sworn by the brand.  I have terrible neck and back problems and love these shoes for the sturdy comfort they provide.  So it was time for a new pair, and I ordered the Bella Clog in a size 8M.  I just received them today and immediately put them on.  What a disappointment!  I have to return these shoes because one is bigger than the other!  My left foot is slightly larger (1/4-size longer) than my right, so I would expect the left shoe to be a bit more snug, which would be OK........BUT! when I tried on the shoes, the LEFT shoe (on my longer foot) was very loose.  The right fit perfectly.  I walked around my office and really noticed the difference in size.  I had read many reviews on the current Ariat styles and other customers had said the same thing!  I couldn't believe it today when the shoes were different sizes.  Now I have to hassle with a return, but there's no way my good money is going towards shoes that don't fit properly.  So sad.  :-(
