Because of all the reviews for this boot, which I really appreciated, I want to leave my own.  Let me first say I gave four stars only because the boot has not yet been pressed into service.

I read through every review.  I am 5-6, very slender, long narrow flat feet.  (Lol, I have to laugh at my self-description).  My calves are 14" (lots of ice skating.....).  I recently started horseback riding, and desperately needed some muck boots for the mud at the stable.  Was using a Target clearance after ski boot - not the best choice, and quite difficult to clean.

After scouring these reviews, I could see the sizing was a huge issue.  I usually wear a 9 in most shoes.  Was delighted to read that these "ran narrow".  Because of that, ordered a 9, and I'm glad I did.  In case it helps anyone else who is very slender with narrow feet and smaller calves --- my suggestion is that you order your regular size.

Aside from the sizing issues, and throwing my hands up, and "just ordering already", these boots are VERY cute.  I have yet to use them at the stable, but that time is coming.  They look very easy to clean.  The colors are rich (I ordered the brown) and the pattern is lovely.  Good luck!
