I tried the side zip boot version of this but my calves were too big.  This was a great second choice.  Still has the knobby sole for getting around in snow and slush, Gore Tex lined to keep the water out, plus the kangaroo leather is very pliable.  Almost no break-in period required. Doesn't look too out of place in my office which is "office casual" dress.  I looked at others but this one had no speed laces.  From past experience speed laces catch on the inside of my pants and I've ripped the hem out of more than one pair of khakis.  Very well made plus my local shoe repair guy can replace the sole when it wears out.  That's not as common these days as it used to be.
