Russian former tennis player Maria Sharapova has invested in California-based footwear brand Wolf & Shepherd, and will also serve as the company's Strategic Adviser.

A spokesperson for the brand commented 'We've always admired and had a lot of respect for how Maria has pursued things on and off the court: as a mother, an entrepreneur, a businesswoman. Maria has a very acute eye and an aesthetic that pushes the envelope and challenges us to think about how to make truly differentiated, comfortable and exciting products that are relevant to everyone today'.
