Functional shoes are getting more and more attention because of the specific functions they have. We walk you through the foolproof way to verify their functionality.
Function 1: Safety (e.g. toe protection, sole puncture protection, upper cut protection, electrical insulation, etc.)
Safety refers to the safety protection to avoid injury.
For instance, an impact test is conducted on the protective area of the shoe’s toe to verify whether the internal height of the toe remains within the required limits after the impact. This test serves to demonstrate the shoe’s ability to withstand crushing forces and confirms its toe protection functionality. The test places stringent demands on the quality of the toe protection, making it a crucial safety measure.
Function 2: Special function (such as antistatic, heat retention, anti-slip, waterproof, antibacterial, etc.)
Special function means that the shoe has a certain aspect of function and meets the requirements of use under certain conditions.
For instance, in cold regions or environments, consumers require shoes that provide adequate insulation to keep their feet warm. However, existing national and international testing standards often fail to accurately reflect the actual thermal comfort experienced when wearing shoes. To address this issue, PFI has developed an internal method that improves upon the international standards by accurately measuring the temperature difference inside the shoes. This enhanced testing approach better aligns with the real-life conditions and experiences of individuals when using the shoes.
Function 3: Comfort (such as breathable, hygroscopic, etc.)
Comfort refers to how the user feels when wearing the shoes.
For example, when shoes are designed to be breathable, they allow for the quick dissipation of moisture, heat, and odor from the shoe cavity. This promotes a fresh and dry environment for the feet, preventing the sensation of stuffiness.
Function 4: practical (internal increase, self-lighting or reflective, no shoelaces self-tying, etc.)
Practicality means that shoes are usable and fit-for-purpose.
For instance, shoes that incorporate reflective or luminous materials can serve as a reminder or warning mechanism when exposed to light at night. This enhances visibility and safety. Additionally, shoes with a swivel buckle closure offer the convenience of easy tightening without the need for traditional shoelaces, which can be especially beneficial for children by eliminating the hassle of tying knots.
In summary, the functionality of most functional shoes primarily lies in the design of the upper and sole. The material used plays a crucial role in determining the effectiveness of these functions, while the manufacturing process and the intended usage environment also exert significant influence.
