Pneumatic Pump For Custom Compression: Unlike regular medical boots for foot injuries, the ManaEZ foot boot features an air bladder embedded in the boot liner to help control swelling and secure fit. The easy-to-use, 2-step valve and bulb system prevents air from leaking when locked, and makes it easier to remove air when released. Do not over-inflate aircells. Universal Foot Boot: The ManaEZ Boot Air cast for foot can be worn on both the left and right foot. For ultimate comfort as you recover, each aircast boot also features a long and wide toe bed design. There’s plenty of room for bandaged or swollen feet, making it the ideal after surgery boot. Tall Walking Boot With Maximum Support: The tall, reinforced plastic shell is supported with molded uprights to protect the leg, foot, and ankle. When fastening, the professional-grade velcro can be customized for fit to ensure the hard boot stays secured. Stimulates Natural Gait: Our CAM walker boot is designed with a rocker foot bottom that allows you to walk naturally with minimal bulk. The cushioned insole absorbs shock to prevent fatigue while the cast padding promotes proper ankle immobilization to prevent further injury as you heal. Air Recovery Boots: The ManaEZ air cast offers mobility, protection, and support for daily activities while recovering from a variety of ankle and foot injuries, including sprain, broken foot, and stable fractures of the foot, ankle, and lower leg.
