PROBLEM TO BE SOLVED: To provide a shoe and a sole suitable for a person who has bow-legs, capable of reducing a load applied to a knee, and achieving falling of a lower leg to inside.SOLUTION: A midsole 1 comprises: a rear end area R supporting a rear end of an inside of a foot and a rear end of an outside of a foot including a lower end of a calcaneus Bc； an inside area M extending from a front end of the inside of the rear end area R to a bone bottom of a proximal phalanx B1 of a first toe and supporting the inside of the foot excluding the rear end area R； and an outside area L extending from a front end of the outside of the rear end area R to bottom bones of proximal phalanxes B4, B5 of fourth and fifth toes, and supporting the outside of the foot excluding the rear end area R. The outside area L comprises an outside first area L1 including an outside edge and a second area L2 near the center, and an average value of compression rigidity of the first area L1 is larger than an average value of compression rigidity of the inside area M, larger than an average value of compression rigidity of the rear end area R, and larger than an average value of compression rigidity of the second area L2.SELECTED DRAWING: Figure 1【課題】膝の負担を軽減し易く、かつ、下腿の内側への倒れを期待し得る、Ｏ脚の人に適した靴および靴底を提供することである。【解決手段】ミッドソール１は、踵骨Ｂｃの下端を含む足の内側の後端および足の外側の後端を支持する後端領域Ｒと、後端領域Ｒの内側の前端から第１趾の基節骨Ｂ１の骨底まで延び、後端領域Ｒを除く足の内側を支持する内側領域Ｍと、後端領域Ｒの外側の前端から第４趾の基節骨Ｂ４の骨底および第５趾の基節骨Ｂ５の骨底まで延び後端領域Ｒを除く足の外側を支持する外側領域Ｌとを備え、外側領域Ｌは、外側縁を含む外側寄りの第１領域Ｌ１と、中央寄りの第２領域Ｌ２とを包含し、第１領域Ｌ１の圧縮剛性の平均値は、内側領域Ｍの圧縮剛性の平均値よりも大きく、かつ、後端領域Ｒの圧縮剛性の平均値よりも大きく、かつ、第２領域Ｌ２の圧縮剛性の平均値よりも大きい。【選択図】図１
