The Back Flex heel from Petzl is an innovative binding system specifically designed for crampons. It provides a reliable and secure connection between the shoe and the crampon, which is essential for optimal performance in climbing and mountaineering. The system is designed for easy handling and adjustment to meet the varying needs of users. Weighing only 0.125 kg, it is lightweight and does not add to the overall load. The use of high-quality materials such as stainless steel, polyester, and polyamide ensures durability and resilience, while the One Size fit guarantees broad compatibility with different shoe sizes. The Back Flex heel is therefore a practical and functional addition to any climbing gear needs.
