COLOR: I purchased the oyster / black boots and when I received them, they appeared 100% black. I was surprised as I was expecting the "oyster" color on the shaft of the boot to appear a slightly different color (i.e., dark grey) than the black rubber foot area. I went back to the box even to see if the shipper sent me the wrong color scheme, but indeed the box was marked oyster / black ... not a huge deal - they still look very nice - just different than what I initially expected to see.

SIZE: I wear a size 7.5 - 8 generally, and I purchased these in size 8.  I have a medium-wide foot, and they are tighter than what'd be ideal. I think these boots are made for narrow feet. (Also, my foot isn't thick, just wider - I'm on the leaner side of average American - size 4, so I imagine the boot would be even tighter if your foot is thicker / fatter). As with another reader, my foot comes up a little bit in the heel when walking. I have plenty of room to tuck jeans into the boot.

WARMTH: I just moved to the Bay Area and these boots do well in colder rain. I also just went spring skiing in Utah, and these boots did really well in the snow / slush. Kept my feet warm and dry. I could start feeling a little coldness though - just a bit - in the snow. I'm not sure these would be the best at keeping feet warm in very cold weather such as winters in Chicago or Minneapolis, but I could be wrong as I've never tested this boot in this type of cold weather!
