The Dynamic Air Walker Boot is our latest walking boot, and it features a closed-toe design. The foam liner has a built-in pump so that no tools are required to inflate the liner and create a custom fit. The boot includes strap retainers to keep the straps in place and the straps fasten in the front for easy application, adjustment and removal. The cushioned heel provides shock absorption, and the rocker bottom sole is low and wide for natural, stable gait. Ventilation in the side panels keeps the inside of the boot cool to reduce microbial buildup and promote user comfort.
