This is set of two very lightweight titanium crutches with forearm cuffs and padded grips. The crutches are designed for long-term use, for example, by a disabled person. They are hollow so, yes, they float. From the tip to the top of the cuff each crutch is 37 1/2 inches high, so they are suited to someone of smaller stature say, between 5' 1" and 5' 6". The combined weight of the crutches is about 3 1/2 pounds.
