Hey Dev ... In general I agree on the "carbon shoe" comment as I am seeing more athletes with lower extremity "issues" than ever. (achilles, calf / plantar fascia / posterior tib etc.) My fist question, "what shoe have you been training in?" ... EVERY single athlete has been doing a significant amount of training in some sort of plated / soft or bouncy / less stable shoe. That said, Jan does a-lot of training in non plated shoes (especially the Hoka Rincon, which he was wearing @ Roth) ... that said, Jan has always had calf / achilles issues across his career. I hope we see him a few more times at full strength!Springy bouncy shoes change our mechanics in terms of stability and the timing of how calf and tibia muscles interact with toes which is totally different from how we all both evolved for running or learned to run as kids (the timing is just subtly different). When we run across a trampoline we have to change some of our timing. That is an extreme example but somewhere in between pure barefoot and trampoline you have carbon plated running dynamics.
It's just slightly different. Does it lead to some injuries ? It's just a hypothesis for now
