Great boots. It took a bit of trail and error to find the perfect fit, so thank goodness for Amazon's return policy.  I normally wear a 10.5D shoe.  After reading numerous reviews on several sites, I went down a half size and ordered a 10D.  But the width turned out to be so narrow I couldn't get my foot into the boot.  10E was the perfect width but I had too much heel slippage.  So I tried a 9.5E, one size smaller and and a width wider than my normal size.  This was the Goldilocks pair--just right.  I wear these pre- and apre-ski.  Great traction on slush, ice, mud and everything else you come across in a ski town. Water proofing was a must and these deliver.  And despite the non-skid sole, they still do well two-stepping.  They also are perfect for trail riding, mucking out stalls, and any other crud related activity.  So despite the challenge of fitting the right fit, the effort was surely worth it.  Added benefit:  the 9.5E was $50 cheaper than my normal size, so there's that, too.
