Learn How to Restore old shoes made of leather in Five Simple Steps Learn How to Restore Leather Boots in Five Simple Steps If your leather boots have been abused, you should probably repair them. If you locate a pair of severely worn leather boots on the secondhand market, you will likely need to repair them. The beautiful thing about high-quality leather boots is that they can always be revived, unless irreparable damage, such as a rip in the leather, renders this impossible. There may be a limit to what you can accomplish since certain restoration and repairs need expert assistance. You'd be surprised, though, at how much you can accomplish to repair leather boots or shoes with minimum supplies and a bit of elbow grease. In reality, the process may be completed in 5 simple stages. As Required, Resoling Or Rebuilding Leather Boots Repairing leather workboats If pieces of the top are starting to loosen, the first step is to resole or rebuild the boots or shoes, if necessary. This is largely your decision. If you're just concerned about your boots' small descent towards funkiness and the tread still has plenty of life, don't fret. If the soles are visibly worn or if you purchased secondhand boots for a project, it is advisable to start from scratch and have them resoled. 
The leather must then be restored to its previous splendor. Decontaminate Your Leather Boots The first step is cleaning the leather boots. Begin by brushing off as much dirt, muck, grit, filth, and soot as possible. Make it as clean as possible. The top is straightforward, but for the welting - where the outsole joins the upper - an old toothbrush is the perfect tool to use. Clean your leather boots or shoes as thoroughly as possible. Apply saddle soap on the boots after you're finished. Saddle soap, if you're unfamiliar, is a leather-cleaning solution made from all-natural components that cleans, hydrates, and nourishes leather. It is the standard leather cleaning product since it works so well. Utilizing a wet sponge or rag, lather the saddle soap. Utilize a circular motion to remove any dirt and debris from your leather boots. Employ a clean cloth to remove the excess. Remove Wrinkles From Leather Shoes Or Boots A pair of badly worn or aged leather shoes or boots will often acquire creases. These are generated by the flexing of leather when walking. Some people don't care about this process, but it's important if you want your boots or shoes to retain their aesthetic aspects. If possible, it is recommended to utilize cedar shoe trees. These strangely foot-shaped gadgets are put into footwear to restore the upper to its former form. If you cannot get them, load your boots with newspaper balls. 
After saddle soaping, your boot leather will be somewhat moisturized and suppler. Here, the leather is heated so that it can conform to the shoe trees or newspaper used to reinforce the shape of the boot. The ideal method involves the use of a heat gun. Get it near enough to heat and soften the leather, but not close enough to cause it to burn. Warm up the creased portion of the upper with a few beautiful, calm, uniform passes. After it has cooled, the wrinkles will have either substantially decreased or vanished. Prepare Boots Using Leather Oil Leather oil is then used to rehydrate, feed, and condition the leather. This replenishes the leather with moisture and adds a layer of protection on top of the leather. If your boots are dry, cracked, and worn as if they owe someone money, it's probable that they have not been oiled or treated with leather conditioner in a long time. Leather should not feel dry; it should feel slightly damp. Simply wipe the boot down until the whole surface is evenly coated and allow it to set for several hours. Then, take them up and examine and feel them. Feel them to be dry? You must redo the procedure. 
Wet leather will darken as a result of its exposure to moisture. That is typical. Once the leather has a little sticky texture, though, it is ready to go on. Lubricate Or Buff Your Leather Boots Next, either lubricate or shine your leather boots. What you should do depends on the boot and what you want to do with it. If you have a pair of casual or vintage boots, you should shine them using shoe polish. You may either polish to a high mirror-like sheen or choose for a matte finish. This is all up to you. If your boots are made of rough leather or are otherwise working footwear, such as a pair of work boots that will be used for work, polishing is unnecessary. In such a case, use boot grease. Apply as you would with oil, remove excess, and let dry overnight. We propose beginning the polishing process by using a cream polish as an additional layer of nutrition and to fill in wrinkles and fissures in the leather. Add a swirling design and coat the whole boot evenly. After creaming, apply a uniform layer of wax polish using a swirling motion until the boot is evenly covered. Buff the polish with a horsehair brush or buffing cloth to get a matte finish. 
For a high mirror sheen, draw tiny swirling circles over the whole boot with a lightly dampened towel wrapped tightly around the index finger. You do not polish the leather; you polish the wax finish. Then, use a polishing cloth to the toe cap and heel to get a high sheen. Allow them to dry overnight, then wear and enjoy!
