An article of footwear flat pattern upper having an upper portion and a footbed portion is provided. The upper portion and the footbed portion are integrally continuous, such that the upper portion lateral side converges with the footbed lateral side. The flat pattern includes nested same-sided article of footwear with a reduced surplus portion there between. The articles of footwear include the following continuous portions: the first medial side with a toe end, the toe end with a lateral side, the lateral side with a heel end, and the heel end with the second medial side. The first medial side and the second medial side are joined to form a dimensional article of footwear.

A protective device, in particular a safety toe cap, for use with an article of footwear is provided. A safety toe cap of the present technology includes one or more strain hardened portions configured to strengthen or reinforce sections of the safety toe cap against impact, particularly from above. The one or more strain hardened portions have increased strength in relation to adjacent non-strain hardened portions and therefore may maintain adequate protection of a user's toes and foot, while simultaneously allowing for lowered material use and a device with a lightweight, streamlined profile.

A method for assembling shoe components includes the steps of: providing at least two shoe components, a shoe last and a film unit; placing the at least two shoe components on an outer surface of the shoe last; removably covering an assembly of the at least two shoe components and the shoe last with the film unit such that the film unit and the shoe last cooperatively define a confining space therebetween; and pumping air out of the confining space and heating the at least two shoe components to shrink and deform the film unit so as to press the at least two shoe components to adhere tightly to each other.
