Frequently Asked Questions
What is overstriding in running?
Overstriding occurs when the foot lands ahead of the center of gravity, causing a braking impulse that sends shock waves through the knee and tibia.
Is 180 spm necessary for all runners?
No. Optimal cadence depends on leg inseam length and speed. Taller runners naturally thrive around 170-176 spm.
