In a method of forming an article of footwear, a shell is formed between at
least two die portions. The shell has a flash line defined proximate an
interface of the die portions and along a perimeter of the shell. The
method may include coupling a component directly to the shell so that the
flash line is at least in part disposed proximate or below an upper edge
of the component, with the component selected from the group consisting of
a midsole and an outsole. The flash line may be positioned to coincide
with an edge of a ridge on the shell.
