I bought these boots about two months ago and they are great.  They are really warm and the soles work well in any type of weather (snow, ice, rain) which was something that I was worried about since they don't appear to have too much traction.  The bottom of the boots were a little hard on my feet so I put in a gel insole, which worked and fit well.  As for the opening of the boot, it's big and roomy.  I have larger calves, which makes finding these types of boots terrible for me.  These give me ample space, and I don't get that scrunchy part on the back of the boot from the shaft being too small for my leg.  They are also really easy to clean up with a mixture of water and vinegar should you live in an area that uses a lot of salt on the sidewalks.  I love these boots!
