Hier mal die Sicht von https://www.scienceofspeed.org/our-t...d-sole-cleats/ , die Markierungen in fett sind von mir:

Mid cleat placement does have merit when it comes to bike fit. The calf muscles do not provide much benefit, regarding propulsion on the bike but act more as a stabilizer for the ankle. We will even place cleats further back on shoes of riders with larger feet to help reduce the lever arm, and ultimately reduce calf strain. With a mid-foot cleat placement you will reduce this more significantly and only moderately utilize the calf for stabilization which should ultimately result in fresher calves for run propulsion.

This mid-foot cleat placement will also result in a lower seat height. As you reduce the impact that “ankling” plays on total leg extension. This, with changes made in cockpit setup will result in a smaller frontal area and mean a slightly more aerodynamic position. Which, in a world of marginal gains, this could result in sizable increases in aerodynamics

Wohlgemerkt sprechen sie hier von Rennradsetup, bei Triathlon dürfte das ein oder andere noch etwas deutlicher zum Tragen kommen.


Auf https://www.triathlete.com/gear/bike...eat-placement/ heisst es dazu

- It takes the calves (always an inefficient means of propelling a bike) out of the equation, thus saving energy otherwise wasted

- Not only will your power increase and your calves thank you, but this cleat position can result in an aerodynamic advantage too, allowing the rider to use a much lower saddle (like 3cm lower), which is a tremendous benefit aerodynamically, and also a benefit for cornering and stability by lowering the center of gravity; it also allows a smaller, lighter bike frame to be used

- Sprinters and riders who climb out of the saddle won’t want them … Otherwise, they are beneficial to any rider who wants to go faster
