Researchers at the University of Pittsburgh have announced the development of a new modeling approach that is said to predict the traction performance of shoe treads. The model was developed by Kurt Beschorner, associate professor of bioengineering, and Seyed Moghaddam, a student researcher, at the university's human movement and balance laboratory, which works on solutions to prevent falling accidents. The lab uses computer modeling to study the friction between shoes and floor surfaces. Footwear that distributes a person's weight over a larger tread area can also improve traction, making shoes safer. The researchers will now start collaborating with footwear companies to design safer shoes using their modeling system.
