Hi'
I was just over at Time Out. The NRS Muckluk is a great winter paddle boot. I have a pair and do like them. Joey said they have a good run in mens size 9 and up. With mine I found this boot fits small. The mens 9 is about a normal size 8. I wear a 9 and had to buy a 10 to get my foot in it. If your a woman with a 9 foot, this 9 will likely fit you. Also, they work best with a with a med weight or better polypro sock which will absorb moisture from sweat. Have a pair along when sizing them.
Don't forget to ask for your 10% LCP discount.
