Dynamic kirigami shoe grip designed to reduce risks of slips and falls

Losing your balance and falling does not just happen during icy Boston winters. The slip resistance of your shoes can determine how well you walk on different surfaces without losing balance. Shoe grips increase friction by engaging with the walking surface, helping to increase stability. In a recently published study, investigators from Brigham and Women's Hospital and the Massachusetts Institute of Technology (MIT) presented a bioinspired assistive shoe grip based on kirigami, the Japanese art of paper cutting.
