An insole for footwear that is capable of providing a protective layer between
a plantar surface of a human foot and an upper surface of a sole of the footwear.
The insole can have a first portion positioned in a rearfoot region of the insole
and a second portion positioned at a forefoot portion of the insole, wherein the
second portion can be more flexible than the first portion. The insole may further
include a toe piece positioned in a toe region of the insole and a footbed that
overlays the first portion of the insole, the second portion of the insole, and
the toe piece of the insole.
