A shoe may comprise an upper and a comfort sole attached to an outsole, the comfort sole having a radius of curvature at any point of a line from a heel to a toe and interfacing with outsole, wherein the lowest point of comfort sole and outsole, called the center of mass or balance point of the sole or natural balance point of the shoe, when placed on a substantially horizontal reference plane defines a transition zone of the roll of the foot having the highest radius of the comfort sole and the outsole, and in that the center of mass is behind point (B) of the metatarsals; and a rigid shell interposed between the upper and the comfort sole.

The present disclosure provides for composite textiles that can include a coating layer that is compatible with textiles such as those comprising polyolefins. The coating layer, as well as the precursor coating layer composition, the coating mixture, or resin composition used to form the coating layer, include a mixture of a polyolefin resin and a thermoplastic vulcanizate (TPV). It is believed that the use of the coating layer in the disclosed composite textiles can promote better bonding between other components or materials used in articles, such as articles of footwear or articles of clothing, while resisting or preventing creasing and bagging. This allows the use of cost-effective materials such as polyolefins in the composite textiles that have adequate physical and mechanical properties, while also having sufficient chemical bonding properties.

A footwear article includes a tongue and a tongue reinforcer, which helps the tongue maintain a shape and position when the tongue is subjected to forces or adjustments, such as from other footwear-article elements or from a wearer. For example, the tongue reinforcer may help the tongue maintain a shape and position when a wearer is inserting his or her foot into the footwear article or when medial and/or lateral quarters press inward on the tongue.

An article of footwear includes an upper, a midsole, and an outsole, where the midsole is located between the outsole and the upper. A wedge is located between the outsole and the midsole and is preferably made of a material that is less compressible than the midsole. A flexible cage is located on the exterior surfaces of the upper and midsole. In embodiments, the flexible cage is designed to limit the outward expansion of the midsole when the midsole is compressed under load, and thus effectively stiffen the midsole. The total compression of the midsole of the article of footwear is based, at least in part, on a desired orientation of the ankle, knee, and hip joints of a user.

An adjustable heel support member includes a base portion and an extended portion. The extended portion comprises a lateral portion, a medial portion and a rearward portion. The heel support member further includes a fastening member that can be used to adjust the lateral portion, the medial portion and the rearward portion to resize the heel support member. In some cases, the fastening member may be an elastic ring.

A shoe may comprise an upper (5) and a comfort sole (9) attached to an outsole (7), the comfort sole having a radius of curvature at any point of a line from a heel (C) to a toe (D) and interfacing with outsole (7), wherein the lowest point of comfort sole (9) and outsole (7), called the center of mass or balance point of the sole or natural balance point of the shoe, when placed on a substantially horizontal reference plane (H) defines a transition zone (Z1) of the roll of the foot having the highest radius of the comfort sole and the outsole, and in that the center of mass is behind point (B) of the metatarsals.

The invention discloses safety toe caps made from nano composite material and a preparation method of the nano composite safety toe cap. The toe caps are made from multi-layers of laminated glass fiber cloth coated with resin paste, wherein the percentage ratio of the resin paste to the glass fiber cloth is as follows: the resin paste accounts for 30-45%, the glass fiber cloth accounts for 55-70%, and the total sum is 100%; the resin paste comprises the following components in percentage by mass: 30-50% of thermosetting resin, 0.1-5% of modified carbon nanotubes, 10-30% of modified nitrile rubber, 5-25% of polyurethaneacrylate, 1-5% of prepolymerized silane oligomer, 0.5-2% of a high-temperature initiator such as tert-Butyl peroxybenzoate, 1-2% of a medium-temperature initiator such as tert-Butyl peroxy-2-ethylhexanoate, 5-20% of a shrinkage-reduction additive, 1-10% of thickener A, 1-3% of thickener B and 2-5% of inner demolding agent. The safety toe caps made from the nano composite material is are high in pressure resistance and impact resistance, light in weight and thin in wall thickness.
