These are very simple boot toppers that incorporate two colors.

They are made so that they can be reversed - with either the 1st color (red in photo) or 2nd color (black in photo) is the top ribbing showing out of boots.

The houndstooth pattern was a technique learned from another pattern and incorporated to cuff shape, credit to:
