Ahh, you're using poser, yah? All you need to do is select both the left, and right foot on the keyframes, and while the specific foot is selected slide it along the appropriate axis, I believe it is Z axis. Just select it, then turn the knob until they are adequately spaced apart from one another (I think the label is "Ztrans")
