Leather shoes benefit from regular polishing, likewise suede shoes
benefit from regular brushing. Kiwi is an excellent brand of polish
which can be found in most shoe shops. A good polish helps to repair
any small cracks or surface scratches on the leather. Additional
use of a cream can also stop creasing.
A quality pair of shoes will have stitching around the sole so
the sole can be replaced if a hole appears in the leather. Likewise
the top piece of a heel is also replaceable for quality shoes. A
good repairer, polish, cream, and shoe tree can extend the lifespan
of top quality shoes over twenty years.
A shoe horn can also be used if you have tight fitting shoes, they
help to avoid scuffing the leather by a forceful entry of the foot.
It's also important not to get shoes with leather soles wet. If
it looks like a damp day then bring out a cheap pair of shoes with
a rubber sole. If you have a selection of nice shoes then alternate
the days you wear them.
The leather absorbs sweat on warm days, and ideally they should
be left for a couple of days to dry. Finally storage, find an area
away from the sun or heat, a rack in the open is ideal. Shoes stored
in a cupboard cannot breath as easily. Also use shoe trees, they
stretch the shoe when not in use and this slows down the level of
creasing and bending of the sole.
