A footwear sole insert comprising: a sheet member configured to extend a length of a wearer's foot and having a uniform thickness, the sheet member having a first face adapted for receiving contact with the wearer's foot, the sheet member having a distal end toward the wearer's toes and a proximal end toward the wearer's heel; a raised ridge face formed at the sheet member first face, the insert having a thickness along all of said raised ridge exceeding said uniform thickness and the raised ridge face configured to be brought into contact with a region of the wearer's foot extending from a vicinity of a cuneocuboid joint area at a proximal edge of a cuboid to a vicinity of proximal phalanxes at an MP joint area between a second metatarsal and a third metatarsal so as to elevate the region and hold the same in archlike form, the raised ridge face extending in a lengthwise direction from a first end away from the distal end of the sheet member to second end away from he proximal end of the sheet member, the raised ridge face extending in a widthwise direction from a first side away from a first side edge of the sheet member to a second side away from a second side edge of the sheet member; a depression formed within the raised ridge face toward a distal end of the raised ridge face to accommodate MP joints in the MP joint area; and a sloping inclined surface formed along the raised ridge face proximal to the depression, the insert having a greatest thickness at a proximal end of the sloping inclined surface.
