Abstract
Footwear and footwear production process includes steps that include the reuse of raw materials previously used in footwear or other sources. The process also provides for the reduction of waste and environmental impact as well as the elimination of water consumption. Footwear includes renewable origin, natural, recycled and recyclable components, being a sustainable product, ecologically viable and inserted in the context of Circular Bio Economy. The footwear presents quality standards in accordance with standard technical standards of quality, overcoming challenges related to obtaining comfortable and simultaneously sustainable shoes.
Claims4
A footwear production process, comprising the following steps:
- (a) cutting a first fabric, thereby obtaining an insole lining;
- (b) cutting a first recycled fabric, thereby obtaining an upper, said upper comprising metal-free eyelets;
- (c) positioning the insole lining on a white latex midsole;
- (d) positioning the white latex midsole on a recycled midsole;
- (e) simultaneously sewing the insole lining, the white latex midsole, and the recycled midsole to the upper, so that a surface of the recycled midsole is exposed;
- (f) bonding a natural material midsole to the exposed surface of the recycled midsole, thereby creating an insole upper, the insole upper comprising, in layered arrangement, the upper, the insole lining, the white latex midsole, the recycled midsole and the natural material midsole, in that order, and so that a surface of the natural material midsole is exposed;
- (g) positioning the insole upper in a format-regulating device;
- (h) adding glue to side walls of a recycled sole;
- (i) bonding the side walls of the recycled sole to lower sides of the insole upper, thereby obtaining a semi-finished footwear;
- (j) drying the semi-finished footwear for a period of time between 1 and 8 minutes, under a temperature between 25 and 60° C.;
- (k) cooling the semi-finished footwear to room temperature;
- and
- (l) adding a removable insole inside the semi-finished footwear and adding laces to the metal-free eyelets present in an upper half of the semi-finished footwear, thereby completing the footwear.
