Bicycle shoe sole

Abstract

A bicycle shoe has an upper portion with a sole attached to the upper portion. The sole has upper and lower outer surfaces that define a toe section, an arch section, a ball section and a heel section with a longitudinal axis extending between the toe and heel sections. The ball section has a cleat attachment area surrounding at least one cleat attachment hole extending between the upper and lower outer surfaces. At least the arch section is configured with a transverse cross section having a center sole area with a first predetermined height, a medial side sole area with a second predetermined height and a lateral outside sole area with a third predetermined height, the first predetermined height being smaller than said second and third predetermined heights. Preferably, the sole upper and lower inner surfaces defining an interior cavity.
