Our Story

Founded in 2019, Flexorainternational began with a simple mission — to help people walk, run, and move with lasting comfort and without foot pain. From day one, we’ve focused on real performance instead of exaggerated claims. Every decision we make is backed by research, testing, and a commitment to proven results.

After more than four years of continuous development and refinement, we’ve proudly served tens of thousands of customers worldwide. Every Flexorainternational product goes through careful design, testing, and verification before it ever reaches your feet — ensuring comfort you can truly feel and quality you can trust.

Quality & Innovation

Each pair of Flexorainternational insoles is crafted from premium Terylene fabric and high-density EVA foam, then subjected to rigorous quality control under both international and in-house testing standards, including:

  • Compression stress–strain testing (ISO 3386-1/-2): Ensures lasting shock absorption and minimal loss of shape.

  • Shore hardness (ASTM D2240): Balances softness with proper structural support.

  • Abrasion resistance (ISO 4649:2017): Simulates 500 km of continuous wear to ensure surface durability.

  • Cushioning and shock absorption (SATRA TM142 & TM183): Measures real-world impact protection, both initially and after repeated use.

  • In-sock friction (SATRA TM184): Reduces slipping and enhances stability within the shoe.

(Note: Tests like ASTM F2913 and SATRA TM144 apply to outsole slip resistance, so we do not label Flexorainternational products as “non-slip outsoles.”)

We also collaborate closely with podiatrists to optimize arch support, heel cushioning, and pressure balance in accordance with BAPO Footwear Fitting Guidelines — reducing fatigue and supporting natural movement all day long.

How We Develop Our Products

  • Research & Design: Guided by clinical foot health data and real-life usage insights.

  • Prototyping & Testing: Each design undergoes at least 8 weeks of testing in both lab and real-world conditions.

  • User Feedback: Over 1,000 testers provide data on comfort, durability, and performance.

  • Continuous Improvement: Every update introduces measurable, data-backed enhancements.

Transparency & Commitment

  • Offering clear sizing charts and precise product information.

  • Showing realistic production and delivery timelines — never overpromising.

  • Backing every purchase with our 90-Day Risk-Free Guarantee — full refunds if you’re not fully satisfied.
