I've been looking for new boots for the past year and finally found everything I needed in one pair. Size 11 fits my 16 inch calf well; this is half to one size larger than I typically wear but with the slip-on style, the extra space in the heel does not bother with this design (required a wider toe box due to a foot problem). Am pleased it is real leather for a good price and without the flaws mentioned in previous reviews. I only wear skirts/dresses so this offers the perfect amount of protection from cold winter winds without 'cooking' me in the warmer stores.
