A strong, lightweight composite material having beneficial flexing characteristics is made using a unique reinforcement material. The reinforcement material comprises a fabric incorporating glass rovings with graphite tows in an architectural combination that retains the properties of both materials. Composite structures made using this reinforcement material with a thermosetting or thermoplastic matrix are extremely lightweight, with desirable anisotropic flexing properties. The finished composite structure is extremely useful as an arch support in a shoe to absorb and distribute the forces generated by walking. In distributing forces on the foot such a support will provide the desired stiffness along the longitudinal axis while allowing increased flexibility along the transverse axis.
