I love these boots for their comfort, water resistance, and tire tread soles.  I usually wear 7.5 normal width shoe.  Most of the boots in my size, I have to wear with a thin sock.  In these boots, I ordered 7.5 wide width due to the reviews I read.  I put inserts in, based on the reviews about a hard heal, and I wear with an athletic sock which keeps my feet warmer than thin socks.  I have a 16" calf and I ordered 4 boots I could not zip up before I found these.  They have elastic to expand for wide calf women, but they fit me perfectly without the elastic expansion kicking in.
