Mephisto Men's Mobils Replacement Insoles for Shoes Natural - Today's shoppers have grown accustomed to purchasing new shoes, wearing them out in a few months, throwing the shoes in the trash, and repeating the entire process. This ends up costing the average shopper several hundred dollars every year. A more practical solution is to invest in quality shoes that can be used for years. Mephisto shoes are made to last a long time on their own, but the life of Mephisto's Mobils can be doubled or even tripled with a small amount of basic maintenance. Periodically trading out the Mobil's original insole for a Mephisto Replacement Insole is a good first step. The Mobil Natural Replacement Insole is constructed from cork and latex. It contours to the foot for a natural fit. The replacement insole is a small investment that can add months or even years to the life of the Mephisto Mobil.
