Intuitively correct: leg direction
The foot should be as close to the crank as possible. The PC2 pedal axle is
designed to allow the feet to be positioned to the crank as close as possible
which improves the power transmission. It also decreases the likelihood of joint
problems by reducing the strain placed on leg structure throughout the pedal
motion. The Inner-Stop helps with orientation and positioning. It also prevents
the shoe scuffing the crank arm.
