Watch the attached Product Video's that show a few parrots using bird roller skates. We highly recommend using Clicker Training to teach your bird to skate. Keep in mind that your bird will be using new muscles as it learns to manipulate the bird roller skates, so keep your training sessions short and have patience as your bird develops muscle tone and motor skills to manipulate the skates.
