A method for manufacturing a sensor insole includes connecting wires of force sensors to a printed circuit board. The printed circuit board and the force sensors are positioned on a felt layer in a predetermined configuration, and placed in the mold. A urethane foam is then injected into the planar internal cavity of the mold to form a sensor sheet that includes a urethane layer, the felt layer, and the printed circuit board and the force sensors positioned therebetween.
