All Strive footwear incorporates our podiatrist-designed "Biomechanical Footbed Technology" which re-designs the classic flat footbed to the natural contours of your feet. Recommended by podiatrists to help improve posture, which may relieve symptoms related to poor foot alignment such as foot, knee and back pain. Sculpting the precise shape of our footbed took months of analysis; studying every curve of the human foot. We worked closely with UK leading podiatrists and drew from the expertise of our custom-made orthotics laboratory, to finalize the design. Thousands of Strives have been purchased by podiatrists from across the world and our sandals have been granted the APMA seal of acceptance. The APMA Seal of Acceptance Program recognizes products that have been found beneficial to foot health. Each Strive sandal has been reviewed by APMA podiatrists to ensure its safety and overall quality.
