The Micrometric Tecno-3 magnetic closure system is designed for ease, adaptability, and minimal weight.

Both the mechanism and retaining clips are easily replaceable for added convenience.

This design enables superb flexibility from front to back while maintaining sturdy lateral support. The combined action of the Tecno-3 magnetic mechanism and the micrometric memory strap allows precise adjustment for the calf muscle's circumference to achieve a personalized fit
