The toe segments are used only as leaf segments for display purposes: they do not have any other function in the model. Therefore, they are aligned with the foot segment, but displaced to have their origins near the LTOE/RTOE markers.

**To define the toes:**

1. Define a line called **LeftFootLine** using the function type **Line** and **From point A in direction of Vector B**.
2. Select A = **LAJC** (the left ankle joint center), change B’s Type to **Segment**, the Input Variable to **L_Foot** and the XYZ to **X**. In other words, the line starts in the ankle joint center, and is defined in the direction of the left foot’s X-axis.
3. Add a new point **LTJC** using Type **Point** and **Project: A onto B**. For A, select **LTOE** and for B, select the **LeftFootLine** defined above.
4. Create a new segment **L_Toe** using the exact same definition as for **L_Foot** already defined except that the origin point should be **LTJC** instead of LAJC.
5. Repeat Steps 1-4 for the right side.
