There are two levels of the Saphir products: Kinda Pricey and Very Pricey. Here is the lower priced option:

Here is the Very Pricey version of the same thing:
Nearly a year in, I couldn’t be happier. It doesn’t scuff easily, and it seems to be mostly resistant to stains. I spot “clean” and polish the areas that get heavy contact - elbows and such - using a very small amount of Saphir Leather Cream
Yep, this one.
Tbh there's a bunch of others like Cadillac leather conditioner and Apple leather conditioner which I read good reviews about but I have not personally tried.
I started using Saphir Renovateur (Amazon Link) recently to freshen up some old leather shoes that I had neglected.
The stuff worked amazingly.
I started using it on other items like belts and watch straps and it works great for keeping the leather hydrated, pliable and to prevent cracking.
Keep in mind, it does use mink oil, so your leather will be darkened by it, but that didn't really bother me too much.
I use AE's lotion ($9). Others use Saphir Renovateur ($12 on Amazon).
I live in Colorado (very dry) and don't lotion all that often since I use the AE "Premium Shoe Polish" that keeps things moist.
IMO, AE stuff works as well as the Saphir stuff but with a lower price and a guaranteed color match.
I think I bought a pair of horsehair brushes on Amazon for ~$14 a while back. 6.5" is plenty big enough. The pics online make the bristles look stiff but they won't be.
Assuming this is for those Churchs you bought - I'd straight up recommend Saphir Medaille D'or Renovateur. The cheapest vendor I could find was in QC
The alternative is the non medaille d'or line Amazon.
Here's another basic conditioner from (Loding)[https://www.loding.ca/en/nourishing-cream-sprays/1582-nourishing-cleaning-cream-for-leather-shoes-3000000011287.html]
Pure mink oil is complete overkill on dress shoes. Good for thicker leather boots/jackets b/c it can make the products more weather resistant + matches the colour tones of the generally darker products.
However, in the end they are just white sneakers so the only things you really need are a cleaning brush (old toothbrush will work), conditioners and maybe some shoe trees. I recommend the (J&M's)[https://www.johnstonmurphy.com/j%26m-cedar-travel-shoe-trees/2054.html?dwvar_2054_color=Pull%20Tab#q=shoe%2Btree&lang=en_US&start=3]
Is this what you're talking about? Maybe I should give it a go. https://www.amazon.com/dp/B002PLC60Y/ref=cm_sw_r_cp_apa_i_EJymFbF1CXXQY
