Welcome to 'The Chamonix Tapes' an inside look at the adidas Terrex Team during the 2021 UTMB. Starting on Tuesday August 24th and running through to Sunday August 29th, there will be a daily podcast release for your audio pleasure. In The Chamonix Tapes 2, we speak with Macy (Marcel Hoeche) and Ekaterina Mityaeva about shoe design and the new, Agravic Ultra shoe. "Sustainability, materials and who is the consumer? Everyone deserves a perfect shoe… From the very beginning we knew we were on to something super great. I can't begin to tell you how many different shapes of the plate we used in so many different materials. If you pair five shapes and five materials this is 25 pairs of shoes we need to test… It was a complex process which was definitely worth it."
