GROUP PROJECT
6 WEEKS | FALL 25 SEMESTER
STUDIO 5 | PARSONS SCHOOL OF DESIGN
This project develops a running shoe that visually reveals when its mid-sole cushioning has worn down, helping runners replace their shoe soles and not the entire shoe before injury risk increases.
The shoe measures changes in mid-sole compression over time and displays that wear in millimetres as a clear, personalised indicator.
The Problem
Shoes have a mileage and thus need to be maintained and periodically replaced. This can be quite expensive and users aren't aware when the shoe should be replaced unless its too late.
What Happens?
The midsole foam gradually loses its elasticity and rebound from repeated compression with each step
Over time, materials like EVA or TPU break down at the cellular level, causing the cushioning to flatten and absorb less shock
RUNNING SHOES HAVE A LIFESPAN OF 300-500 MILES

The Direction
The rate of change of compression height would measure the use of the shoe over the duration of it wearing down.

Unit of Measurement
Key features
1. A replacable midsole to prevent viable parts of the shoe from going to the landfill.
2. Measurable wear for midsole.
