It is 364 kilometres (226 mi) long, and its drainage basin covers 11,700 square kilometres (4,500 mi²). It flows southwest to meet the Samara Bend of the Volga near Sokolyi Mountains, north of the city of Samara. The major tributary is Kondurcha.

Europe's oldest pottery was found on the banks of the Sok River (see Elshanka culture for details).
