Good boots are not cheap. Cheap boots are not good. As a utility lineman, I spend a lot of time outside under harsh conditions at work. My boots, while tough (they have to be), often pay the price as I slog through mud, water, snow, salt and rocks, not to mention the beating they take while wearing steel climbing hooks and abrading against a telephone pole. There is, however, a way to delay the inevitable and preserve your boots to survive at least as long as this crappy economy.
Step 1: The Basics. Start With Oil.
Maintaining your boots is not difficult or expensive, but it needs to be done at regular intervals.you could expect to double the life of them by doing regular maintenance. Here's what you need: Neatsfoot Oil-there are plenty of oils and creams out there that all promise to do various things.
Step 2: Brush.
A cheap plastic brush-use this anytime you have dried mud or dirt on your boots or shoes to clean off excess grit. You don't want to be rubbing dirt into the leather as you oil them if you don't have to. A towel, blanket, or lots of newspaper-this is a messy job, and unless you can work outside where it won't get on carpet or fancy floor coverings, you'll want one of these to protect your floor.
Step 3: A boot dryer
This is a lifetime investment if you buy right-capable of drying a pair of heavy leather boots overnight, this item is also good for your gloves, hats, etc. that get wet in either rainy or winter weather.
Step 4: Get Started.
Pull your laces out of your boots. Put the boot over your hand,normally white residue is road salt along the seam where the upper meets the sole. Brush this off as well as you can-we want to concentrate on this area, as the stitching will fail if the leather is not kept supple here.
Step 6：Dry. Wipe. Maintain.
Take your boots and place them in a quiet corner overnight-most of the oil will soak in, leaving just a little residue by morning. If you like, you can wipe off the excess with an old cloth towel or paper towel, either one will work. You also want to dry your boots out as often as you can， prevents premature failure of leather and stitching.
Hope this was helpful. Walk tall, work safe.
