I get really, really into cleaning shoes. I have both of those pairs as well, along with others. Scrubbing bubbles, Armor All, Saddle Soap, Shoe Polish, Hairspray, Water - The list goes on and on. There are so many different ways to clean shoes (in general), and too many different products to use, so it's really just about finding the best way personally to do it. I'm very efficient and thorough, and can make the shoes look brand new practically. I might over-do it sometimes, but oh well. Here are my methods for each:
After a game, of course they are dusty/dirty. Initially, I spray them down and all around with a Lysol All-purpose Oxy spray (Walmart, like $2.50) instead of scrubbing bubbles, just a preference. Then I kinda let them sit while some of it runs off, taking a lot of the dirt with it. Then I wipe them down pretty good. Next, I spray the "Original" Armor All spray all around and rub that in, to moisten and start the shining process. If I'm really feeling it, before this I will saddle soap them with a sponge and then rub it all off with a rag, then apply the Armor All. - From there, (For the NB460 plate shoes) I will take black shoe polish or parade gloss with a toothbrush and go over the "N" threading on the plate, to keep it black and not dirt-colored. This is key to keeping it like that, as sometimes the cleaners don't fully do the job. Then I'll buff it all off with a horsehair shoe brush. - By now, the shoe is pretty dry, but I'll go over it again with a rag to dry off. Then I'll apply a light layer of black shoe polish cream all around, until it's good and in, then let it dry. I make sure I don't get it on the white or on the silver N logo, if so, wipe it off good, just don't let it sit and stain. Here Is when I usually stop, and let them rest until dressing before a game. Then I'll polish them down with a standard black shoe sponge and you're good to go.
The white sole on the base shoes just takes more elbow grease and scrubbing, and generally you can keep them very white. I've heard of using toothpaste, but I haven't tried that yet. Another thing, for either shoes, it to use shoe bags. I use the Honig's shoe bags for my plate shoes (each) when they are clean, helps keep off dust and other dirt form your bag. Also, cedar shoe trees do wonders. They can soak in moisture after you've worn them, keep good shape, and keep out smell.
Like say, I'm very thorough, and probably over do most of it, but it works and it's just how I do my shoes. Take what you want of it, but no matter what, keep our shoes clean! It makes a good first impression when walking on to the field, and just overall completes a professional look as an umpire.
