As many of us have been preparing for the Kieser Great Ocean Road Running Festival this weekend there is one element to consider that has a big impact on our runs - our shoes! 

Today Tim Dettmann sits down with Sam Zielonka who is a product manager for Mizuno shoes.  Sam takes us through the history and development of sports shoes and answers some of Tim's burning questions around shoe technology. 

For all of you who want to know more about the history behind the different types of sports shoes and the difference between the levels of support - this episode is for you!
