I have been completely addicted to Fit Flops since my first pair 7 months ago.  I purchased a pair of clogs during the summer to help me transition into winter, but they were the old style and they were big and clunky because I ordered a half size up, also they won't work with skirts.  I ordered a pair of the suede boots, but promptly returned them as they were too casual for my dresses.  I found a store carrying the mukluks and determined they were too hot for constant wear in Atlanta, but I determined I did need to order a half size up.  I ordered the tall boots in black and SCORE!  They are nearly perfect.  They aren't as hot as the clogs (go figure), the ankle and leg area are big enough for me to wear comfortably.  I have a vascular problem which often leads to ankle swelling, and my calves don't fit in about 80% of typical boots.  If you have a really large calf, these probably won't work for you. I have a size 9 boot and my calves are 15 inches in circumference.  If my calves were any bigger, they wouldn't fit comfortably.  The style is just dressy enough to get by wearing them with dressy skirts and dresses.  They aren't SUPER stylish, but they WILL work.  Same fabulous comfort, reasonably good breathability, and sturdy.  They might be too tall for anyone shorter than I am (5'4").
I am once again in love and thank Amazon for the sale which brought us together.
