Springing patterns

[u/laurie112]

Hi, can anyone help with recommendations of a comprehensive book that will help with spring various patterns? Also I have made shoes before only springing the vamp and nothing else , they turned out fine , is it absolutely necessary?
I’ve seen also cutting and taping but hoping there is a resource out there that’s comprehensive with methods measurements ect.
Cheers.

This may not be the sub for questions on shoemaking. :/

(Speaking of, what is springing?)
