US Patent 10238316 Passive five sensor insole real-time feedback device

A feedback device determines when a person has placed enough weight upon his/her foot to safely take the next step, and then communicate that information to the person via a haptic device on the person's ankle or an audio, visual and/or vibration feedback display on an application on the person's smart phone. Five sensors in an insole between the person's foot and shoe determine the force of the person's leg. The five sensors in the insole will be positioned under the heel, the fifth metatarsal head, the first metatarsal head, the space between the second metatarsal head and the third metatarsal head, and the hallux (big toe).
