So far, these are very nice boots.  Although, my first pair needed to be replaced because the pull string at the top snapped (but could have been my fault since i pulled it pretty tight).  They are very warm.  There is an inner wool liner that keeps your feet/legs warm.  The only downside is that the boots run bigger than normal shoes.  Even with thick socks, they feel too big.  I didn't replace the size because I feared the size down would be too small.  I don't use them for anything other than shoveling/snow blowing, so it's not like I am trekking miles in these.
