I’ve got Northwave GTX “Artic” boots. The artic just means they’re the same as the normal ones except have a fleece liner.
I still tend to wear a sealskin type (aldi) waterproof sock off road for added protection, I’m going to wear a thick sock anyway, it may as well do two jobs, after 7 years the northwaves might have a pinhole leak in the toe area that leaves my toes clammy, but TBH it could just be sweat. They do benefit from a liberal dose of reproofing spray so it could be a small leak that’s mitigated by just keeping the surroundings water repellent.
Gripgrab gaiters over the top. Effectively makes them waterproof to everything short of total immersion at which point water finds it’s way up between the two flaps, onto the tongue and up under the gaiter.
like anything I think the solution is layers and keeping dry. On the road I find thick socks, summer shoes (tape over the sole vents) then overshoes works perfectly well. The north waves just combine all three layers in 1.
