Abstract
The present invention provides a sole contact body for footwear such as a shoe, an athletic shoe, or a sandal. The sole contact body comprises a raised part which is configured to contact each of the second, third and fourth toes to lift the metatarsophalangeal and proximal interphalangeal joint positions thereof, and which is configured to fit between the first and fifth toes so as not to lift the first and fifth toes throughout the entire lengths thereof. The raised part is configured to have a first toe-side stepped surface that touches the side of the first toe closer to the tip of the first toe than the metatarsophalangeal joint position thereof, and a fifth toe-side stepped surface that touches the side of the fifth toe closer to the tip of the fifth toe than the metatarsophalangeal joint position thereof.
