Pneumatic Pump For Custom Compression: Unlike regular medical boots for foot injuries, the Royal Air 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 Royal 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 walker boot supports the limb with full shell protection, and is reinforced with molded uprights to protect the leg, foot, and ankle. It also has ventilation panels, which allow the internal liner to stay dry and cool. When fastening, the professional-grade velcro can be customized for fit to ensure the hard boot stays secured. Fracture & Cast Boots with Athletic Design: Our CAM walker boot has a rocker foot bottom with treads for traction that adds safety and support, allowing you to walk naturally on all surfaces. 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 Royal Boot Air cast provides 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.
