A fastening device includes a case, a spool and a knob. The case includes a housing and a base. The housing includes a receiving space and two side holes communicated with the receiving space. The base is detachably connected to the housing. The base includes a continuous wall, and the continuous wall surrounds a lower edge of the housing after the base is connected to the housing. The spool is received in the receiving space and configured for a lace passing through the side holes to be wound therearound. The knob is disposed on the case. Rotating the knob relative to the case in a fastening direction causes the spool to rotate in the fastening direction for fastening the lace.

An upper is provided for a shoe. The upper is basically provided with a base layer, a first reinforcement layer and a second reinforcement layer. The base layer includes a toe portion and a heel portion. The base layer has a joint free three-dimensional shape at least partly defining an interior foot receiving space. The first reinforcement layer is disposed on an outer side of a centerline of a toe-heel direction of the upper. The first reinforcement layer overlies a first heel area of the heel portion. The second reinforcement layer is disposed on an inner side of the centerline. The second reinforcement layer overlies a second heel area of the heel portion. The first reinforcement layer and the second reinforcement layer are separated at the heel portion.

A method of forming a printed structure is disclosed. The method may include printing layers of a printed structure and incorporating an element within the printed structure. The element may be removed in order to form tunnels within the printed structure. In some embodiments the element may be removed and reused in the formation of additional printed structures. The element may also be retained to form a composite printed structure.

A fastening system includes a sleeve having a cylindrical body, and one or more braking members provided on the sleeve. At least one strap is extendable through the sleeve and movable relative to the sleeve while the sleeve is braced. The one or more braking members resist movement of the at least one strap relative to the sleeve.

A system for securing shoes to the feet using a single pull shoe closure arrangement. Each of the various embodiments utilizes a transverse strap arrangement that extends between the lateral and medial sides of the shoe across the tongue or top portion of the shoe. The transverse strap is a single, generally flat, strap extending from one side of the shoe across the top portion of the shoe to the opposite side where it joins with a single pull sub-system. The preferred embodiments use a single pull system oriented longitudinally along one side of the shoe to draws upon one end of the transverse strap configuration to affect the shoe closure. Alternate embodiments pull a shorter draw strap laterally to a point of securement on the side of the shoe below the tongue area without the need for a longitudinal pull motion.
