1. The Birth of COPPERFINGER

We asked ourselves a bold question:
"How can we maximize the benefits of copper?"

Copper has long been celebrated for its antibacterial, deodorizing, and health-enhancing properties. However, incorporating copper into an entire sock posed significant challenges in terms of cost and efficiency. We needed to be strategic. So, we began brainstorming:

"Where is copper needed the most?"

The answer was clear: the toes!
Toes are not only hotspots for sweat and bacteria growth but also critical areas for blood circulation and overall foot health. With this realization, we decided to focus our efforts on embedding copper where it could make the most impact.

The result? A sock that combines innovation with practicality: COPPERFINGER.

2. Why Copper?

A Targeted Design

COPPERFINGER socks were designed with a unique focus: the toe section. Instead of spreading copper fibers throughout the entire sock, we concentrated them in the area that needs them most—where sweat accumulates, bacteria thrive, and blood circulation plays a vital role.

• Toe Section Innovation: We used a special blend of fibers containing 33.3% copper in the toe area. This high concentration ensures maximum antibacterial and deodorizing effects where they are most needed.

• Comfortable Body: The rest of the sock is made from soft, breathable cotton, providing all-day comfort without compromising functionality.

This combination of targeted copper application and high-quality materials resulted in a product that is not only functional but also cost-effective.

3. The Big Question: Does It Work?

Even after completing COPPERFINGER socks, we wanted proof that they worked as intended. Specifically:

• Would the socks release measurable amounts of copper?
• Would our innovative design deliver on its promises?

To answer these questions, we partnered with a laboratory to conduct rigorous testing.

4. The Experiment: Measuring Copper Release

(1) Objective

• Verify whether COPPERFINGER socks contain detectable levels of copper.
• Ensure that the released copper aligns with our design specifications to provide effective antibacterial and potential health benefits.

(2) Methodology

1️⃣ Sample Preparation
We cut out only the toe section from COPPERFINGER socks to use as test samples.

2️⃣ Artificial Sweat Solution
To simulate real-life conditions, we created an artificial sweat solution by mixing water (H₂O), sodium chloride (NaCl), and lactic acid. The solution was adjusted to a mildly acidic pH range of 4–6, mimicking human sweat.

3️⃣ Immersion
The samples were submerged in the artificial sweat solution for 24 hours to replicate conditions where sweat interacts with the sock during wear.

4️⃣ Copper Concentration Measurement
After 24 hours, we used ICP-OES (Inductively Coupled Plasma Optical Emission Spectroscopy) to measure the concentration of copper ions (Cu²⁺) released into the solution.

5. Results: How Much Copper Was Released?

The experiment revealed remarkable results:

• Approximately 5090 mg (5.09 g) of copper per kilogram of fabric was detected.
• This translates to about 0.509% of the sock's total weight, confirming that a significant amount of copper is present and active.

Interpretation

• The concentrated use of copper fibers in the toe section successfully released measurable amounts of copper.
• This level of copper is sufficient to provide strong antibacterial and deodorizing effects.
• Specifically, it is highly effective in areas like toes, which are prone to sweating and bacterial growth.

6. What We Learned: A Design Success

This experiment scientifically validated that COPPERFINGER socks deliver on their promise. Here’s what we achieved:

✅ Maximized Copper Efficiency
By focusing on embedding copper in only the toe section, we achieved both cost efficiency and performance optimization. Instead of spreading copper across the entire sock unnecessarily, we targeted where it’s needed most.

✅ Antibacterial & Deodorizing Properties Confirmed
The results demonstrated that COPPERFINGER socks effectively inhibit bacterial growth and reduce odors by releasing active copper ions (Cu²⁺).

✅ Exploring Vasodilation: A New Possibility
Through this experiment, we uncovered another exciting potential benefit: vasodilation (blood vessel expansion).

7. Copper and Vasodilation: Unlocking New Potential

The interaction between sweat and copper fibers releases ions that may penetrate the skin and stimulate blood vessels. This opens up fascinating possibilities:

• When blood vessels expand due to vasodilation, more oxygen and nutrients are delivered to tissues.
• For athletes or individuals on their feet all day, this could mean reduced fatigue, faster recovery times, and enhanced performance.

Imagine your toes receiving a steady supply of oxygen-rich blood while you run or train—this could translate into:

✔️ More Energy
✔️ Greater Power

While this theory needs further exploration, it’s one that excites us deeply—and one you can experience firsthand by wearing COPPERFINGER socks.

8. For Athletes: A Game-Changer

COPPERFINGER socks aren’t just about hygiene—they’re about performance.

• Enhanced blood flow in the toes can improve endurance during long runs or workouts.
• Faster recovery means you can train harder without worrying about fatigue.

Whether you’re chasing personal records or simply staying active, these socks are designed to support your journey.

9. Conclusion: Experience It Yourself!

COPPERFINGER socks go beyond antibacterial and deodorizing benefits—they introduce a new possibility for improving blood flow through vasodilation. However, this theory is best proven by you!
