If you're using boots in temperatures between 70 and 90 degrees then gore-text is not good, IMO. In those condition if you step in water and you have good socks like the others have mentioned your feet and boots will dry and on their own and breathe much better. Gore-tex in hot weather will make your feet sweat. Sweaty feet = blisters.
After a day of desert hiking in gore tex my feet are soaked from the inside out. Much prefer unlined boots unless i absolutely need them for wet conditions.
