Abstract
Footwear with vertically lapped nonwoven layers in upper and sole structures for enhanced breathability and moisture wicking is disclosed. Exemplary vertically lapped nonwoven dual layers comprise one or more hydrophobic layers and one or more hydrophilic layers that are adhered to each other by a plurality of methods and are further integrated into the inside of the upper and sole of the footwear so that the hydrophilic layer is in direct contact with the feet. The hydrophilic part of the dual layer wicks sweat or bodily fluid from the wearer into the nonwoven and transports the moisture to the hydrophobic layer for fast evaporation, thus keeping the feet dry. The nonwoven footwear is environmentally friendly as the nonwoven layers can be made of recycled materials and may be fully recyclable.
