These footcuffs are suitable for both men and women with a maximum size of foot size 44 (UK size 10). The maximum weight per suspension is 50 kg, so a total body weight of 100 kg. These cuffs can be worn in two ways. 1: with the D-rings at the top side of the foot, ideal to have footrests in a sling. 2: At the bottom of the feet, for someone to hang or if someone is laying on his or her stomach, to lift the feet.  Perfect to live BDSM nights without limit.
