Force Lasting
A lasting process where the insole board or Strobel sock (usually canvas or non-woven) is stitched around the last bottom edge to complete the upper. Usually used for more lightweight, flexible shoes such as running shoes. Also called slip lasting.
In the force lasting process, the shoe last is “slipped” or “forced” into a heated upper.
