Arachna Foot insoles are customised to control the way the foot functions and correct biomechanical imbalance. Controlling the way the foot functions can be helpful in treating certain foot conditions and in relieving pain symptoms through the correction of posture and supporting the underlying muscles and tendons. Biomechanical imbalance can also cause injuries in other parts of the body due to certain muscles overcompensating to achieve balance. Slight trimming with scissors may be required to obtain just the right fit in some boot styles. If you spend long hours on your feet, work on hard surfaces, or are just big on comfort, a pair of great insoles will be your secret weapon against injuries and fatigue at work. Over time, your work boots will lose some shock absorption, cushioning and stability. You can keep using them, but the level of stress and impact on your legs, joints, and feet will grow, meaning more chance of injuries, and more chance of feeling tired and sore. A good, fresh pair of insoles will make your work boots fit better, and make them a whole lot more comfortable.
