NOTE!  MY ORIGINAL REVIEW WAS FOR NIKWAX AQUEOUS WAX TREATMENT, NOT SURE HOW IT MIGRATED TO THIS PRODUCT

That said, I've tried several Nikwax products and they are all good.

I'm probably more demanding of my footwear than most. I hike in the winter, dog sled, sled, build igloos, and generally spend a lot of time with my boots in wet snow and mud.

I've tried silicone sprays and treatments - useless except for keeping mud and salt stains off your dress shoes. I was using SnoSeal and Edelrid DrySkin or Mink Oil but have found this stuff to be a lot better, easier to apply and more durable.

I use Nikwax aqueous wax on my dress shoes, you can get a decent shine on top of the AW.

I've also used it on gloves (Grandoe Sympatex) with success. You can apply to wet leather which makes it very handy since applying mink oil or the other heavy grease treatments to wet leather is useless. Since this stuff is water based it soaks in to where the leather is more porous and leaky.

Why might you need to use aqueous wax on goretex shoes or gloves?  Because the outer leather can get waterlogged, even if your toes and fingers stay dry.  Waterlogged leather is slippery - not good for gloves.  Aqueous wax gives a tacky feel.

Good stuff.
