Love these boots!  In Northern California, I wear lightweight boots all winter, so a good pair is imperative for me.  I'm not heavy, but sometimes I have problems with the circumferance of some boots--they're just too tight around my calf, so I can't tuck in jeans.  I bought these boots in my usual size (8M) and they were comfortable right out of the box.  I've worn them constantly, both tucked in with jeans or leggings or with thights or dresses and skirts. The buckle on the side adds a little extra cachet, and I've received lots of compliments.
