I've had two hip implants, i still wobble a little and sometimes i've fallen, is there any kind of shoes i can buy to prevent falls in that situation?

Exercise more import: Feeling unsteady after hip surgery is most likely due to muscle weakness about the hip. Pt is important to strengthen the muscles. More uncommonly the prosthesis could be loose. I would recommend getting x-rays and starting exercises around your hips. In the short term, a cane or walker would steady you and low heeled shoes with velcro straps would help support your feet. You should be eval.
