When I started caring about shoes the first thing I bought were shoe trees. They play a big role in making sure your shoes live a long life so you can get more wears out of them.
Cedar wood is known for its aromatic properties so it deodorizes and absorbs moisture. In the event they become drenched in rainwater you’ll see the wood absorb the water in a matter of minutes after sticking it inside. Another benefit is that they prevent creases from becoming permanent. In worse cases these creases can lead to cracks in the leather – something you absolutely want to avoid.
The best deal I’ve found so far locally are from MUJI (shown above). They retail for PHP 1,250 and are suitable for a wide range of footwear. It features a spring-loaded split toe so it fits evenly. It’s not the best shoe tree out there but for the price it’s hard to beat.
