Waterproofing and Stainproofing 

A protective spray is an excellent way to protect your shoes from water, snow, mud, and spills. The best way to protect your shoes is to wipe the leather with a damp cloth, following the instructions on the protector spray. Spray your shoes before wearing, and on a regular basis thereafter. 

Wear and Tear Prevention 

If you plan to use your shoes frequently, you may want to consider a trip to the shoe repair shop. It's a smart idea to have shoe taps and possibly rubber soles put on new shoes as a way to postpone the gradual wearing out process that comes with normal use. Think of your shoes as tire on a car, the tread will wear after many miles and may need replacing...

Maintenance 

Finally, we highly recommend cleaning your shoes on a regular basis, depending on frequency of use. The cleaning method depends on the shoe's material.
Leather can be polished and conditioned with a leather lotion applied with a soft cloth.
Suede looks best when brushed; although special suede brushes are available, a clean toothbrush works just as well.
Fabric should be sprayed with a stain guard.

In addition, shoes-- particularly those made of soft nappa leather-- benefit greatly from shoe trees, or shoe keepers. These are wooden instruments which are inserted in the shoe, and they help to retain the shape and mold of the shoe. Shoe Trees can help to prolong the life of a shoe by 4 or 5 years.
