Kg's Boot Guard Brush on Toe... https://www.amazon.com/dp/B008SK1X8W?ref=ppx_pop_mob_ap_share
I have a bad habit of dragging my trailing foot on sidearms. This leads to my shoes getting a whole on the toe after only a couple months of use. This stuff is a epoxy/rubber blend that comes in a liquid that you spread on with a brush. It has extended the life of my shoes by a whole year by just reapplying every month or so. (Yes I know this is a form problem and I have spent plenty of time in the field trying to fix it but for some reason it always comes back. So for now, this is my bandaid fix.)
Hey I have those exact boots! First, DO NOT oil or wax your boots as others have suggested... YET. That will come later.
The best toe protector is KG's Boot Guard. I have it on my zamberlans and it has held up perfectly for hundreds of miles. It is tough, semi flexible, and stays flexible at very cold temps (hiking in snow/snowshoeing is no prob). You prepare the surface, brush it on, let it dry. Very simple process. Contrary to what another poster said, you can easily not only meet, but exceed the manufacturer's rubber rand durability with this product. My brother has the 960 GTX which you linked in the second image, and his rand isn't holding up as well as my KG Boot Guarded toebox.
First you will want to clean the leather really well with a leather cleaning product and a soft toothbrush. Let it dry completely (48 hours is best) before proceeding.
Since your toes are already scuffed, you have pretty much done the abrasion step in the application process. They include a piece of sandpaper for scuffing up the area which helps with adhesion. You will want to still knock off the larger clumps of leather with the included sandpaper though, and make it an evenly abraded surface. Here is what mine looked like at this stage.
Next you will brush on the boot guard. I intentionally kept it off the major flex point of the toes, which I think has helped with the durability. I don't know how well it would hold up if you covered an area that folds or wrinkles when you walk. Here is how mine looked after application.
After it dries, you will want to then treat the rest of the leather. I highly recommend Leather Honey if you just want to recondition the leather. If you want to seal it with a wax based product, then skip the conditioning step and go straight to the wax sealing (sno seal is pretty much the best). The third option is the zamberlan conditioner/sealant product HYDROBLOC, which is what I used, and have been extremely impressed by it. It did a great job of both reconditioning the leather and sealing it (of course the boots have gore-tex, but this stuff makes water just bead off like sno seal does).
Best of luck to you, I hope I replied before you applied any kind of conditioner or sealer. Once those go on, you basically have no chance of the KG Boot Guard adhering to the leather sufficiently.
What if you pre-coat them? You can get the purpose made stuff, but IIRC some guys just get them shot with a couple coats of bedliner.
