Claim 0:
1. A footwear comprising a sole having an upper surface on a side configured to come in contact with a bottom of a foot and a bottom surface on a side that touches ground,, wherein in a longitudinal cross-sectional view of the sole,
an angle β is an angle between a straight line L1 and a plane a ground surface plane that the bottom surface of the sole is in contact with, and ranges from 35 degrees to 75 degrees,
an angle α is an angle between a straight line L3 and the ground surface plane that the bottom surface of the sole is in contact with, and ranges from 25 degrees to 65 degrees,
a contact point A is positioned closest to a toe side of points where the bottom surface of the sole is in contact with the ground surface plane,
a point B is a point of the sole closest to the toe side,
the straight line L1 passes through the contact point A and the point B,
a line L2 passes through the contact point A and is perpendicular to the ground surface plane that the bottom surface of the sole is in contact with, and intersects with the upper surface of the sole at an intersection point C,
the straight line L3 passes through the intersection point C and the point B,
the angle α and the angle β satisfies the relation 1≤(β/α)≤1.5,
and a height of a toe spring is 7 cm or more and 14 cm or less.
