The Columbia Minx was a little more fashionable than this tomboyish Sagittarian liked but the need for a lightweight boot was paramount. I purchased this boot and was blown away with delight. It really is lightweight. Fits nicely on my size 9 foot. Insert here that you do need to buy a size or size and a half bigger. I bought a 10 and with a regular wool sock it fits with no extra room. I would have in retrospect bought a 10.5. I feel the little bit of foot wiggle room would help with reflective warmth. They are toasty. The temp here has't gone below 20 degrees so I will update on the real warmth later. I enjoy wearing them and the extra fashion furry top makes me look hot.
