The present invention discloses amethod for preparing a nanocomposite material for toe cap production. The nanocomposite material is made of graphene, carbon nanotubes, fiber composition, a silane coupling agent, acetic acid, acrylate rubber, a dispersant, polyethylene resin, nano-silicon carbide, calcium stearate, zinc stearate, talcum powder, modified boron nitride, a curing agent and other materials. The preparation method is convenient and simple and is suitable for large-scale production; the nanocomposite material has high toughness and strength and good water resistance, wear resistance and aging resistance; all materials have a good combination effect with the fiber composition, therefore the nanocomposite materil has good mechanical properties and a light weight.

A method of customizing a boot, for example a skate boot, includes generating a tridimensional digital representation of a wearer's foot using numerical data obtained by scanning the wearer's foot. A boot with a foot size corresponding generally to a foot length of the wearer's foot is selected. A core is also selected. The core, a medial side insert and a lateral side insert are inserted into an internal space of the boot such that the medial side insert and the lateral side insert straddle the core. The medial side insert and the lateral side insert are manufactured based on the tridimensional shape of the foot. At least a portion of the boot is then heated such that the boot is thermoformed to follow surfaces of the medial and lateral side inserts. The core, the medial side insert and the lateral side insert are then removed from the boot.

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.

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 includes 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 dimensional article of footwear.

A method of method of manufacturing customized inserts for a boot, such as a skate boot, that is at least partially thermoformable includes receiving numerical data corresponding to a tridimensional shape of a wearer’s foot, and manufacturing a medial side insert and a lateral side insert based on the tridimensional shape of the wearer’s foot. The medial side insert and the lateral side insert are shaped to be insertable into the boot with a core that is dimensioned to generally correspond to a foot size of the boot, with a medial internal surface of the medial side insert and a lateral internal surface of the lateral side insert abutting respective outer surfaces of the core.
