I purchased a previous incarnation of these Miz Mooz slouch boots about 5 years ago.  I LOVE my old pair, and have worn them for EVERYTHING, all year round, so was excited to find that they're still available in an updated version.  I am not sure I like these new ones as well.  The lining on the shaft of the older slouch boots was a mesh fabric inside the leather, which made them super comfortable and breathable, even in hot weather, and the leather upper and lining still look almost new, after 5 years of hard wear (lots of dancing, city walking, even mountain hikes and desert dwelling).  These new ones have a light fake fur lining, which is soft and comfortable with short socks, but probably not as durable or versatile as the mesh, and likely to make you sweat in hot weather.  The shaft on my old pair was the perfect size; snug around my calves.  These are a bit baggy.  I am a size 0-2,but muscular, so maybe have smaller than average calves.  I think the sizing runs a little large.  My old pair was European size 37 and fit perfectly.  These are 7s, which are supposed to be equivalent, and I think I may need a 6.5.  I usually wear a 7-7.5.  Bummer.  The leather is nice and Miz Mooz quality and style is great.  But I am a little disappointed and may have to return these.
