I have always been curious. I have hammer toes, no pain involved. So probably no too severe. I wonder if I did not have them, if I could run better. The toe off phase might be stronger? Am I just reaching here?
Yes, you are "reaching"
Many people have "hammertoes", clawtoes, malletoes, contracted digits, etc. They don't need addressed unless you are like the description below where the biomechanical deformity is beginning to cause pathologies. So run happy and run fast!
