spring-loaded knee booster brace

Spring Stabilization: It typically features three to four carbon steel springs that act as a rebound system. These springs absorb energy when the knee bends and release it during extension, effectively assisting the leg muscles.

Pressure Reduction: The mechanical assistance can reportedly lighten up to 20kg (44lbs) of pressure from an individual's own weight per pad, or roughly 40kg total for a pair.

Breathable Design: It is often constructed from SBR or OK fabric, which is perforated for breathability and includes non-slip material to keep the brace in place.
