#89 Flexible vs. Rigid Forefoots with Kofuzi!

#89 Flexible vs. Rigid Forefoots with Kofuzi!

Matt and DJ are joined by a very special guest, Michael Ko (aka Kofuzi)! Kofuzi tells us about his background and the growth of his YouTube channel. They take a look at his journey to 100,000 subscribers and what's next for his channel. Finally, they investigate the effects of a flexible or rigid forefoot-the biomechanics implications and what type of runner may want each kind of shoe.

Today’s episode is sponsored by Running Warehouse! Right now there are Memorial Day promotions going on with discounts on many types of products through the end of May. Make sure you check it out. Also, coming soon, Running Warehouse will have the ASICS METASPEED SKY+ and EDGE+ in stock on June 1. We will be testing and putting out full reviews on these models soon!
