By request here are some images of footed shafts. These are from the late great arrowsmith and friend of my fathers- David Cartwright formerly of Goodrich Ontario Canada.
David was a true craftsman and was the owner of Arrowmaker Traditions.
A footed shaft is an arrow reinforced at the front end by splicing a stronger, denser piece of hardwood (such as walnut or purpleheart).
This enhances durability, and adds weight to the front of the shaft as well.
These below are both v cut joints and are made on 23/64ths Ramen wood shafts.
The footings are purple heart on top and Brazilian Rosewood on shaft below.
He has taken several deer with these with no breakage.
