An article of footwear may include an upper configured to receive a foot of a wearer and a sole structure fixedly attached to the upper, the sole structure including a ground-contacting outer member and a removable midsole. The footwear may further include a motorized tensioning system including a power source, a control unit, a tensile member, and a motorized tightening device, the motorized tightening device being attached to an outer surface of the upper, and the tightening device being configured to apply tension in the tensile member to adjust the size of an internal void defined by the article of footwear. In addition, the power source and the control unit of the tensioning system may be configured to be removably disposed in the removable midsole.

A strobel for an article of footwear contains ETPU. The article of footwear and a process for manufacturing the article f footwear are also provided.

A footwear sole comprises an first sole portion including at least one protruding male engagement part and a second sole portion including at least one recessed female engagement part having a shape which closely conforms to that of a corresponding male portion, whereby when a force is applied to the first sole portion in the direction of the second sole portion, the corresponding male engagement part is fixedly retained by the female engagement part. In this manner a shoe-sock may be fixed to the second or another portion of the sole without the need for any adhesive to be used.

Manufacturing and assembly of a shoe or a portion of a shoe is enhanced by automated placement and assembly of shoe parts. For example, a part-recognition system analyzes an image of a shoe part to identify the part and determine a location of the part. Once the part is identified and located, the part can be manipulated by an automated manufacturing tool.
