WHAT IS CAST SHOE AND ITS FEATURES: These medical walking boots protect the foot and/or ankle after injury or surgery while allowing you to move around. These are often used after surgeries to the mid- or forefoot or to protect the region after stress fractures of the foot severe lower ankle sprains or other injuries where the foot has to be bandaged or immobilized via a cast. It can also be used without a cast or bandaging though you may want to wear a sock with the boot to prevent the Velcro area from rubbing. OUR SPECIAL FEATURES: The post-operative shoe's insole is constructed of EVA (ethylene vinyl acetate) which is a shock-absorbing light material that supports the foot. It's also considered more eco-friendly since chlorine is not used in its production. ADVANTAGES OF WEARING CAST SHOE : The wide squared insole acts as a buffer for protection when you're moving about. The open and squared nature of the toe-region makes room for bandaging a cast and swelling. The openness of the toeless surgery shoes improves their breathability keeping the foot cool. HOW IT WORKS:Protects the plaster cast of the foot from soiling and wetting Protects feet from mechanical damage HOW TO WEAR IT :Start by placing the injured foot inside of the shoe. Wrap the main forefoot closure across the foot and attach its Velcro closure to the hook material. Then repeat the step first with the strap at the base of the ankle and then with the strap a little bit farther up the ankle.Take a few steps to make sure you have the closures tight enough that the foot does not slide around in the boot but loose enough so that it doesn't cause pain or cut off your circulation. Adjust the fit as needed. Note that for ease of application you can switch the side that the brace closes on. AVAILABLITY AND SIZES: Available in 4 sizes SMLXL.
