Three different jobs that get treated as one. Cleaning removes, conditioning feeds, polishing covers - and doing them in the wrong order undoes all three.
Leather is a fiber structure held flexible by oils and fats. Every wet-dry cycle takes some of those out; so does salt, so does detergent, so does time. When enough have gone, the fibers stop sliding past each other, the leather stiffens, and the flex point across the toe cracks. That crack is permanent - there is no product on earth that closes it.
Everything in this section is about not getting there. It is genuinely simple once the three jobs are separated, and most of the confusion in the shoe-care aisle comes from products that do two of them at once without saying which.
Lexol
One of the few conditioners whose maker publishes a reapplication interval.
Skip it if: You are conditioning suede. Liquid conditioners flatten and stain a napped surface.

Do them in that order, allow drying time between each, and a pair of boots will outlast several rounds of the alternative. Polish, cream and wax explained properly is a page of its own - they are not interchangeable and the tin rarely says which one you are holding.
Several excellent products permanently darken leather, and their makers say so. Atsko states that Sno-Seal will somewhat darken all leather. Mink oil and pine-tar greases darken heavily. Bickmore sells Bick 4 specifically on not darkening. If the color of your boots matters to you, that is the first question to ask about any tin, and it is usually answerable from the manufacturer’s own page in thirty seconds.
Lexol publishes an interval - use every six months for ongoing care - and most makers do not. The useful signal is not a calendar, it is the leather: if it feels dry and papery rather than supple, or if the flex creases have gone pale, it wants conditioning now regardless of when you last did it. A boot that has just been soaked or salted always wants it.
Everything above is about smooth leather. Napped leathers - suede, nubuck - are a dry-cleaning discipline: a crepe rubber block, a brass-and-nylon brush, and as little liquid as you can get away with. Conditioners and waxes flatten the nap and stain it. The suede method is separate.
Leather care closes the chain. Conditioned leather takes a waterproofing treatment better and holds it longer, which means the boots stay drier, which means they do not start to smell and the salt has less to attack. That is the whole loop, and it starts here.
