An orthotic boot comprised of highly durable polymer material which is light weight and very durable for limb protection. There are locks positioned on the medial and lateral sides of the foot portion and the shin portion to secure the device to the limb; locks are made out of stainless steel to prevent rusting. There is a breathable inner foam lining within the device that provides comfort and allows the skin to breathe. There is a durable stainless steel hinge positioned at the tip of the foot portion of the device that allows the device to open and close. The sole is constructed out of non-skid material for stability and safety. There is a energy return system built into the sole for maximum propulsion during walking; a gel containing air pockets is compressed during walking and returns to its normal shape when the foot is lifted releasing the stored energy.
