After searching online and reading tons of reviews, I settled on these amazing Helly Hansen boots for our ski trip. HH has a reputation for making quality products (have HH ski jacket too) so I didn't hesitate to purchase.  I wear a 9.5 in running shoes and ordered that very size in these boots.  The fit is perfect and without any areas of discomfort.  The length and width are perfect for my feet with a medium thickness sock  They are warm and so very comfortable (like slippers) so I can highly recommend without any doubts. I expect to get many seasons out of these boots.  Enjoy!
