Abstract: An article of footwear includes an upper and a sole structure attached to the upper. The sole structure includes a frame attached to the upper with frame exterior and interior surfaces defining a frame internal cavity. The sole structure further includes a midsole member disposed within the frame internal cavity and that is formed via a supercritical foaming process. A lattice-work structure of the frame is formed by a plurality of apertures extending through the frame exterior and interior surfaces such that at least some portions of the upper and the midsole member adjacent the frame interior surface are exposed through the plurality of apertures.

Abstract: The fiber-drawing furnace includes a graphite tube positioned vertically, heated by induction, and subjected internally to an inert atmosphere, said tube internally defining a fiber-drawing chamber. In the furnace said graphite tube is a double-walled tube having an inner wall and an outer wall, its inner wall is porous and separates the fiber-drawing chamber from a peripheral chamber defined between the walls and subjected to a flow of inert gas which diffuses through said porous wall into said fiber-drawing chamber. Application to drawing down an optical-fiber preform.
