What is a last and how does a woman's differ from a man's?

A last is the shaped form usually made of wood or synthetic materials that fills the inside of footwear during the manufacturing process. Footwear is built around lasts that are shaped like feet. The last is vital in determining the fit and feel of the boot or shoe. The Women’s last at LOWA are narrower in the heel and thus proportionately wider in the forefoot, slightly higher toe box and have a higher instep.
