A bicycle shoe has a sole portion including an inflection point substantially in a longitudinal central portion of the sole, an inflection point front portion having a convex shape in front of the inflection point, and an infection point back portion having a concave shape behind the inflection. A heel portion having a convex shape for fitting to a heel is continuously and smoothly connected to a back end portion of the sole portion; left and right side portions are smoothly and continuously connected to corresponding left and right side portions of the sole portion and to the heel portion; and a toe portion is smoothly and continuously connected to front end portions of the left and right side portion structures and to the sole portion. The toe portion has a contour line that is closed within a lateral cross section thereof and which has a convex shape, and a radius of curvature of a longitudinal cross section of the toe portion is approximately equal to a radius of curvature of a toe disposed in that position.
