Abstract
A golf shoe (1) comprises a sole portion (an outsole) (3) and an upper portion (5). The sole portion (3) is formed of an elastic material. The golf shoe (1) has a toe side flexibility evaluation value (Gt) of 0.0015 to 0.0100. The toe side flexibility evaluation value (Gt) is calculated by the following equation (I); Gt=(20/L)/Ft (I) In the equation (I), L represents an overall length (mm) of the sole portion (3). Furthermore, Ft represents a tensile load (N) required for fixing a half part of the sole portion (3) close to a heel and pulling a front end close to a toe, thereby displacing the front end by 20 mm.
