For years she had to deal with stress fractures and other injuries as no shoe properly fit, but now after a long trial and error process with custom shoes she is finally on the right path, and has been injury free for 18 months. At the Ironman World Championships in Kona she will compete in the second generation of the Biomac shoes crafted for her by Götz Heine. A light offering in pink with a mid-foot cleat position.

Paula Newby-Fraser was one of the early adopters of the mid-foot cleat position, and we noticed Daniela Ryf in Dubai with that setup as well. Several other Brett Sutton athletes also subscribe to this position, as it gives the rider a less acute angle in the hips and knees.
