The shoe provides an indication to the wearer when forces on the foot exceed pre-selected upper limits or do not meet pre-selected lower limits. The design includes a body member that attaches around the wearer's foot, featuring an exterior sole and an interior sole portion covered by a rigid foot plate. The foot plate has an upper support surface for contact with the foot, and the interior sole portion contains at least one cavity for a force sensing unit. This unit is connected to an electronic means that processes signals from the strain gage, allowing for real-time monitoring of foot pressure. The display unit alerts the wearer when the pressure exceeds or falls below safe thresholds, aiding in the therapeutic rehabilitation of injured lower extremities.
Another notable invention is the "Shoe Construction for Use by Diabetic Persons." This shoe is designed for individuals with diabetes or foot ailments, where excess pressure can lead to ulceration. The shoe features relieved areas on the inner surface that contact the foot, where force sensing resistor units are mounted. When pressure against these sensors reaches a critical threshold, an alarm is activated to warn the wearer, allowing them to take preventive action to protect their feet.
