A walking boot and a boot frame. The boot frame can be formed to receive the walking boot. The walking boot can be secured within the boot frame via one or more buckles. The walking boot can have an externally mounted tongue that can be tensioned via the use of one or more laces and associated tensioning mechanisms. The tongue can be molded to conform to a user's foot and leg while the tensioning mechanisms secure the user's foot and leg within the walking boot. In some embodiments, the boot frame has an open heel to capture the walking boot. In some other embodiments, the boot frame has a rotatable heel configured to pivot away from the toe and receive a heel of the walking boot for easy coupling of the walking boot to the boot frame.
