Most men's hunting boots start at size 8.
As mentioned above, Kenetrek makes a women's line-up that might work depending upon the width of your feet. Scarpa, which I swear by, and other serious mountain hunting boots, also have women's sizes.
Something to consider...a lot of Gore-Tex membrane-type boots have a liner that is not really bonded to the outside of the boot, whether it's leather or technical synthetics. Water will readily penetrate the exterior and be forced up against the water barrier membrane. This of course can and does eventually fail (I burned through 4 pair of Kene's in 3 years and they all leaked like a sieve). But, oftentimes that membrane just "feels" wet if you were to reach in and touch it with your hand, especially if it's cold outside, but is actually doing a decent job of keeping you from getting soaked. And, you might just be feeling your own perspiration since the osmotic and heat differential that the membrane requires can't work optimally and keep up.
Good luck finding a boot that will work for you. If you live on the westside, you might duck into Feathered Friends and see what they have available. REI is just down the street. Once you get the right size, you might be able to find them online for a better price.
