i wanted a water-proof boot, but settled for these because i liked the style.  the fleece lining keeps your feet warm - so warm that on a milder winter day my feet were sweltering.  And my feet are always cold!!!

I haven't tested them in the water - don't think i will.  I did buy a water-proofing cream to keep them in good shape for next winter.

Fits true to size.  i'm an 81/2-9 and the 9 fit fine with thick socks.
