UOG Heavy Duty Anti-Puncture Insole feature advanced Black Diamond Carbon Technology, enhancing blood circulation, boosting recovery, and delivering long-lasting comfort. How does this technology work? Black Diamond Carbon Technology emits beneficial wavelengths that stimulate blood flow and improve circulation. This enhanced circulation helps deliver oxygen and nutrients more efficiently to muscles, reducing fatigue, speeding up recovery after physical activity, and boosting overall energy levels. Additionally, Black Diamond Carbon Technology strengthens the material's resilience and comfort, providing lasting support while helping to prevent odor for a fresher experience during extended wear. It promotes stress relief and relaxation by supporting the body's natural recovery processes, making these midsoles and insoles ideal for everyday use, fitness activities, and long hours on your feet. UOG Midsole & Insole are designed to naturally enhance your wellness, performance, and comfort—wherever life takes you.
