[0005] BACKGROUND OF THE INVENTION

[0006] Traditionally, wearing shoes requires the use of one or both hands to widen the ankle opening and hold the rear section in place while the foot is inserted. Once the foot is inside, additional adjustments such as tightening laces, fastening zippers, or securing straps are typically required to achieve a proper fit. This conventional process can be particularly challenging for individuals with physical limitations, such as back pain or disabilities affecting hand mobility. Studies indicate that approximately 619 million people worldwide experience back problems, making it difficult for them to bend down and wear shoes comfortably. Similarly, individuals with hand disabilities may struggle to secure their footwear effectively, further emphasizing the need for an improved solution.

[0007] To address these challenges, several hands-free shoe designs have been introduced, aiming to simplify the process of wearing shoes. For instance, the invention disclosed in US20150216252 features footwear with magnetic closures, where a shell structure includes a heel section and a front section separated by lateral and medial slits. Magnetic closures are incorporated to facilitate the opening and closing of the shoe. While this design offers convenience, its reliance on magnetic closures may limit the shoe's stability and long-term durability.

[0008] Another invention, disclosed in US 11185125, describes footwear with a sole structure comprising a front midsole component and a rear midsole component connected by a groove in the lower sole . The rear midsole component pivots relative to the front component, allowing the shoe to transition between an open and closed position. While this mechanism improves accessibility, it introduces complex pivoting elements that may compromise ease of use and increase the likelihood of mechanical failure. Additionally, the footwear cannot be adapted for all types of shoes like boots and high-tops due to the height of the shoe, which results in shoes being consistently loose from the upper front this part is called tongue.

[0009] In addition, WO2023049414 outlines a rapid entry shoe mechanism that utilizes a multi -action counter to achieve a two-stage transformation of the shoe’s upper. This design facilitates hands-free donning once both the first and second transformations are complete. Although this design enhances convenience, it still relies on multiple mechanisms, which increases complexity and creates potential points of failure.

[0010] Despite these advancements, existing designs continue to face limitations such as intricate mechanisms, dependency on magnetic closures, complex spring mechanisms, or reliance on multiple steps for proper operation. These approaches often fail to provide an optimal combination of simplicity, stability, and durability. In light of these challenges, there remains a need for an improved shoe closing and opening mechanism that simplifies the footwear application process while ensuring secure closure and reliable performance.
