That's a really good question because we were talking about medial foot contacts because that's one that everybody loses, right? So, think about being on the extreme outside edge of a foot. Okay. That would be representative of sort of the extreme barrier of your base of support. Like you tip over outside of your fifth met head, your toes, right? You're going somewhere, right? Okay. So you think about extremes of inversion, like it's this one point in space where all this density comes in, it's your center of gravity, that's as much inversion as you could possibly demonstrate, so much to the degree that there's so much compression that you can't see any eversion. Okay. Take the fifth met head and reverse that engineering process. This is the greatest representation of space away from midline. It is the last representation of eversion with no inversion. It's like, again, if you fall outside of that base of support, you have no downforce. So you have to fall. Okay. So when we're capturing foot cues, we don't really talk about the fifth met head all that much because most of the time you don't have to practice capturing, you have to just practice hanging onto it. Because again, most people will have pressure on the lateral aspect of their foot in many cases. And so as you're capturing the medial contacts, the mistake that some people will make is that they will over-react to capture medial contacts, and then they lift up the lateral aspect of the heel, and they lift up the lateral aspect of the foot, which releases the fifth met head from the ground. Because what we want is a foot that can do that with the foot on the ground. So that's all the concept. So I want a foot that can do that. And that requires that I have my two heel contacts and my two met head contacts. Typically because of the way that the center of gravity is shifting, we tend to lose our medial contacts. Because again, we're going to move away from midline to find spaces to move. And then that's why we lose them.
