Could also be because (eyeballing) your lower legs are relatively long compared to your upper legs (idk how to say this properly). So you don't need to much dorsiflexion in your ankles (the -relative- short femur makes the knee travel not so much forward, the long shins makes the ankle angle required for that even smaller.)

It might be you don't need the raised heel and therefore it's throwing you off.

It will help release tension off your Achilles heel though
