Newcomers to bondage should experiment with Velcro ankle cuffs. They are easy to attach and remove. More experienced bondage practitioners may prefer to use lockable ankle cuffs. They give greater power to the dominant who keeps the key.
Ankle cuffs are designed with comfort in mind. The padding reduces the risk of nerve damage and other injuries, but they still have the potential of harm. Using them as directed and never leaving the cuffed person alone can minimize the risks. Traditional ankle cuffs are also not designed to carry the weight required for suspension bondage. Specialized cuffs should be purchased for this purpose.
