Title: MIDFOOT-EQUIPPED SOLE FOR ARCH SUPPORT AND PLANTAR PRESSURE REDISTRIBUTION
Abstract:
The invention stated herein concerns a solution for shoe soles which are adaptable to plantar arch morphology. The solution is essentially characterized by combining. Into a single sole. Arch support (4) internally as an integral component of the sole (2) and an insert (1) having a smaller young's modulus than that of the remaining sole (2) externally as an integral component of the sole and confined to the midfoot region (3). This combination of characteristics, which increases the contact area between the foot and the shoe, at the insert of the sole, provides for a more effective damping of plantar forces and leads to a more efficient solution regarding the redistribution and decrease of the maximum forces that act in the midfoot region.
