i just sold my tall uggs on ebay because i want to get short ones instead. the tall ones are great because they keep you warm, but if you ever want to wear your jeans OVER the uggs, rather than tucked in, it's a bit more difficult.
also, i voted for chestnut because i love the color! it adds warmth to those dreary winter days with all those dark, dull colors like black, gray, dark brown, etc.
