I thought Urad made my boots really gunky. The best way to get a good shine is with regular old fashioned shoe polish and a good buff. Kiwi or a similar brand is best and a lot cheaper than all that gimmicky stuff!
Well first don't ever clean with saddle soap or many of the leather products we use for saddles...for whatever reason that seems to make boots lose their ability to shine. For general conditioning and often a shine I've always had good luck w/Vogels leather conditioner- in the beige/yellowish bottle. But for a great shine I've got to agree w/the Kiwi, brush, elbow grease with some help from old pantyhose. I don't think the creme polishes shine as well as Kiwi. if boots are muddy or dirty just use some warm water, rag/old toothbrush to clean (condition w/ Vogels) and then polish
If they are truly gunked up with manure/sweat, etc...I clean them with castile soap, not saddle soap.
I maintain 5-6 thin coats of regular Kiwi shoe polish, replacing as needed. For an occasion requiring REALLY shiny boots, nothing beats Parade Gloss buffed with a nylon stocking. Unless you have access to a military PX, Parade Gloss might be hard to find, I ordered some from Amazon. I spit shine only the toe, it's too time consuming to do the whole boot, but it is cool to be able to check your hair in the toe of your boot .
I have traditionally shined my boots with two coats of Kiwi Parade Gloss buffed up with a shoe brush. However, my current boots, Ariat Crowne Pros, are frustratingly dull no matter what I do or how much elbow grease I use. As soon as they get dusty and I wipe them before entering the ring, they look dull again. So, my friend told me about a cheat product to get them mirror-like shiny. Use a liquid product like Kiwi Honor Guard in black. I only use it on my boot shafts and not on the foot part or or the inside of the shaft where my leg contacts the horse. Once the product dries, it leaves a lasting, high gloss shine. For the rest of the boot, I still use my regular parade gloss method, and I like to add some saddle-tite where I grip the horse for good measure. I went from dull boots to gettign compliments on my shiny boots at every show and with much less effort!
The Honor Guard stays on through multiple show weekends. To strip the polish, which is quite durable, I use acetone.
