I don’t go snow sledding all that often. But when I do, the last thing I want is cold wet feet. Instead of putting down the money for a pair of snow boots, I improvised with a $7 can of rubberized undercoating and an old pair of boots. After the day was over the coating had come off where the leather creases but my feet were still dry and warm. How’s that for being a cheapskate, I mean cheap boot.
There are many shoe "greases" such as "Dubbin". Even petroleum jelly can be worked into the leather. Lots of outdoor workers use this to keep boots in condition for years.
It dries out almost immediately (after cured/whatnot), it's not the least bit flexible, and it ends up flaking right off.
If you haven't tried it, don't.
One other time I wasn't able to go to a tire shop so I used pop rivets after drilling holes, it worked well too.
Regarding the water proofing of leather boots, we usually use special grease for this application in Sweden. There are several kinds, sold in any shoe store or shoe makers/mending shop. It makes the leather supple and water proof. Just clean and dry the leather, smear the grease on thick and let dry/soak in. Wipe of the excess and polish with regular shoe polish. Then you can walk in puddles all day long without getting wet.

Isn't it bright red or something though?
This is a pretty solid idea for the folks who don't need snow boots every day - nice thinking!
