Supersole
When thinking about insoles and sneaker wear & tear, most people think that runners replace their shoes when the tread becomes too thin; however, SuperSole discovered that the lack of comfort on the inside of the shoe prompts runners to dispose of their current sneakers and purchase new ones. Typically, running shoes only last 300-500 miles, which equates to 2-3 months of use. Because of the short lifespan of running shoes, purchasing new high-quality running shoes 4-6 times per year is expensive and generates unnecessary waste.
