I bought this boot after my brother-in-law bragged about how great his Irish Setters were. I will say after all the hype, I was disappointed in the women's line. I believe quality is there in the boot, but I would like to let customers know that these boots are tight, tight, tight. I ordered a size bigger due to the fact I have 4A wide feet (for those who don't know, it is one width size above normal shoe sizing). So, I usually order my size in wide or just go up a half size and that always works. So, I ordered a size bigger (size 10) to accommodate my size 9.5 wide feet. These boots still were incredibly tight on the sides of my feet so I had to lace every other hole while I'm "breaking" them in. I thought maybe it was just me being I have a 4A wide foot, but my sister bought the exact pair for deer hunting and she bought a size bigger (7.5 when she wears a 7) so she can wear thick hunting socks with it - she was surprised how tight the 7.5 were on her with a thin pair of socks (she does NOT have wide feet). She had easily an inch of clearance in front of her toes and they were still tight on the sides of her feet - to the point her middle toes were going numb. She took them back because they wouldn't fit her needs and buying an even larger size (size 8) would have her in an extremely out-of-proportion shoe. So just be aware - they are narrow. I am keeping mine because I believe I can get them to stretch out and break in.

Depending on use, the shoes can be warm - probably good for use up to 0 degree weather WITH moderate activity. I used them sitting in a deer blind for four hours in 25 degree weather (F) with 20 mph cold winds, wore a double layered sock (cotton for first, fleece for second) and put feet warmers in and my toes still got incredibly cold. So would not recommend the 600 thinsulate boots for low activity - aka tree stand hunting/blinds/etc in cold weather. Later, I wore them with a thin pair of socks and shoveled snow for an hour in 13 degree weather with no wind and my feet stayed nicely warm.

So to sum up - Shoes are on the narrow side. Great for cold weather with moderate to heavy activity that keeps your temperature up; not recommended for cold to extreme cold weather with low activity levels.
