The main differences between tennis shoes designed for different surfaces is that the outsoles feature different tread patterns, optimizing traction on a specific surface. Clay court tennis shoes feature a herringbone tread pattern, while grass court soles have small pimples and hard court shoes have thicker rubber reinforcement in high wear zones. These different outsoles can allow for a much appreciated traction enhancement when moving around the court.
