Footwear Article and Knitted Shoe Upper and Manufacturing Method Thereof

Abstract

A footwear article includes a sole and a knitted shoe upper secured to the sole. The knitted shoe upper includes a knitted fabric including a plurality of portions knitted from at least one yarn and a plurality of inlaid strands. The plurality of portions include a front portion, an instep portion, an inner lateral portion, an outer lateral portion, and a heel portion together to enclose a three-dimensional space for receiving a foot. The plurality of inlaid strands are inlaid in the knitted fabric along different directions of the three-dimensional space, so as to restrict relative displacements of the knitted fabric toward the front portion, the heel portion, and the instep portion.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The invention generally relates to a footwear article and a knitted shoe upper and a manufacturing method thereof. Particularly, the invention relates to a footwear article and a knitted shoe upper and a manufacturing method thereof, which restricts relative displacements toward different directions.2. Description of the Prior Art[0002]Conventional shoes made of leathers or polymers are generally poor in ventilation due to the materials used and may sometime even cause uncomfortable feeling. In the conventional shoe-making process, a large amount of materials will be wasted during the cutting, jointing, trimming processes likely to cause environmental issues and also increase the manufacturing cost. Therefore, owing to better stretchability and softness, knitted shoes have quickly developed and gradually occupied a place in the market.[0003]However, in intense sports, such as basketball and soccer games, the actions of sudden...

AI Technical Summary

Benefits of technology

This patent describes a new way of making a knitted shoe upper and a method of manufacturing it. The shoe upper has special strands embedded within the fabric to strengthen it and provide support. These strands are placed in specific areas of the shoe to enhance its strength and protect the foot from injury. The embedded strands reduce displacement of the shoe and help it maintain its shape, making it more comfortable and stable while walking, running, or playing sports.

Problems solved by technology

Conventional shoes made of leathers or polymers are generally poor in ventilation due to the materials used and may sometime even cause uncomfortable feeling.

In the conventional shoe-making process, a large amount of materials will be wasted during the cutting, jointing, trimming processes likely to cause environmental issues and also increase the manufacturing cost.

However, in intense sports, such as basketball and soccer games, the actions of suddenly running, stopping, and jumping frequently occur, so the sports shoes made of knitted upper tend to cause undesired displacements of shoe upper due to its high stretchability and softness, likely to cause injury of the wearer.
