Concept - Sustainable Running Shoe

In the course of a training season, serious marathon and distance runners may have to replace their running shoes every 3 months, not because the soles wear out, but because the thick foam midsole inside the shoe gets compressed and loses its resiliency, compromising the critical support that the runner’s feet need. The Solay concept running shoe has a modular, removable midsole that can easily be swapped out by the runner whenever they need a new one, thus prolonging the life of the shoes by several months, and allowing the runner to train in shoes that have become comfortably broken-in. The result? Fewer shoes thrown into landfills.
