UGG boots are amazingly warm & comfortable footwear for the wintertime. In my opinion, the people who call them "uggly" are people who don't own a pair themselves because they'd know there are A LOT of different styles—even flip-flops—different patterns, colors, etc. If you've owned a genuine pair, the only real cons are price & maintenance. They're clearly not for everyday or for walking through snow & storms. My UGGs did last long, but I made a mistake & didn't maintain them properly. Real fur from sheep or lamb + water = a bad idea. I admittedly didn't use any of the UGG brand cleaners & just threw them in the washer whenever they needed washing. They did come very clean again, but the fur obviously didn't look as good as it did when I first got them. I've owned a couple pairs & would definitely repurchase.
~*Don't let anyone on MakeupAlley make you feel bad about wearing animal skin/fur/leather. Anyone who uses &/or wears perfume, lipstick, nail polish, mascara, eye shadow, soap, makeup bases & foundations, shampoos, shaving soaps, moisturizers & skin care products, lip balm, sunscreen, etc. doesn't have the right to whine about UGG boots because he or she probably smear animal fat &/or byproducts on their faces.*~
Note: If you're going to purchase a pair, consider checking out "Rethink Pink" (Breast Cancer Limited Edition)—it's October & they have signature classics that benefit Susan G. Komen
