The Athlete's Foot CEO Michael Cooper is set to depart from his role after 29 years.
Cooper will also leave his role as the chief of parent company, RCG Corporation, and resign as an executive director.
"This decision will allow Michael to further leverage his skills, experience and capability in a way which he has been unable to do within the new operating structure of the combined group," RCG Corporation said in a statement.
"Michael will be leaving having ensured that the TAF business is well positioned for future growth.
"He has led the key strategic process undertaken over the past 18 months and will leave the business with a clear vision for the future."
Ant Hudson, The Athlete's Foot national sales and operations manager has been promoted to the role of CEO of the footwear chain.
