BEWARE!  Slippery when wet!  With a name like Muck Boot I expected much better traction!  I ordered these $100.00 boots because I work in wet conditions all day.  I have only had the boots a few months and only work thhree days a week and the traction, what little there was to start with, is all but gone.  I looked at the bottom of my boots today and the ridges are almost completely smooth.  I spent the money because many of the reviews were good.  I don't know if I got a knock off pair or what, but they claim to be original.  They do not fit as welll as I had hoped either.  I wear a 61/2 wide in women's and these are still wide on me.  I couldn't have gone smaller or they wouldn't have been long enough.  The arch support is somewhat present, but definitely not what I read in the reviews.  I won't purchase them again.  Way too much money for way too little.
