The Mueller knee brace is a long lasting and effective knee support with a unique design for providing firm support. The knee brace is designed with an inner sleeve with an hourglass shape for firm support and comfort. The durable and hard wearing HydraCinn fabric is latex-free and neoprene-free, and has an antimicrobial protection barrier. This means it is breathable, lightweight and soft, and designed with comfort in mind. This comfortable brace provides support for stiff, weak or unstable knees, as well as protection after injury. The Mueller knee brace has anti-slip inner grip strips to prevent brace migration, and the flexible steel springs support both sides of the knee, but still allow leg flexion and extension.
