A footbed for sport footwear made of a shell, which defines the general
shape of the footwear. The footbed has a sole portion and a padding wall
for partially separating the sides and back of a wearer's foot from the
shell. The padding wall partially cups the wearer's heel and extending
from the back of the wearer's foot along each side of the heel, along each
side of the midfoot and along each side of the forefoot. The footbed is
adapted for determining the size of the footwear in terms of width. The
footbed may further comprise a toe wall portion for determining the size
of the footwear in terms of length.
