If you own a fine pair of welted shoes you will certainly want them to look good for years. While no shoe lasts forever, there are things you can do to prolong the life of your shoe. Along with proper cleaning and creams, one of the best ways to preserve your shoes is by using shoe trees. Why? When shoes aren't being worn they quickly begin to lose their shape. Shoe trees hold the original shape of your shoes and keeps them from creasing and even cracking. Additionally, if a shoe is not worn for a long period of time it can actually shrink, shoe trees prevents this. Finally, everyone's feet perspire and that moisture can cause the leather lining to deteriorate. Cedar naturally absorbs this moisture plus its fresh aroma helps eliminate any odor.
