About this 3D model

To prevent my shoes from tearing at the heel, this insert provides an extra layer of protection. I have lost too many shoes to heel tear, but no longer. These Seavees will last me a long time now. Printed in Ninjaflex on a Taz 6, this insert fits the exact contour of my shoe. I suspect it will also fit well in many other shoes of this style. There are many more ways I can refine this, but I'm happy with this as a first rev. Let me know if it fits well in your shoe!
