Intelligent footwear

This invention describes a smart shoe that can change how it feels and performs while you walk or run. It does this by splitting the force from your foot into two parts: one part is stored, like in a spring, to give you a boost when you lift your foot, and the other part is absorbed. A computer inside the shoe adjusts this split, altering the shoe's dynamic characteristics.

Why it matters: Filed before miniaturized, low-power microprocessors and advanced activity sensors were common in wearables. Today's integrated electronics and efficient actuators make real-time dynamic adjustment feasible within a shoe.
