I've just coated my boots in Nikwax aqueous wax after getting wet feet in the Chilterns today. Weather forecast said some sunshine and heavy showers. Ha! It was actually drizzle and heavy showers, also very windy. (Good practice, though, for when I go to Scotland in a weeks' time and Wales in about three weeks.)
Are you all users and fans of this stuff, or do you have a preference for something else? It doesn't seem to be effective for long, and my little brain is thinking if it soaks into the leather when it's wet, isn't it going to get soaked back out when they get wet again?
