An assembly, preferably for use near the ankle, preferably made, at least in part, of a soft buoyant flexible material is disclosed. The assembly has two basic forms. The first basic form is a band that wraps around the user's lower leg above the user's ankle joint above, or in one embodiment, on the user's foot gear. This form of the assembly has a mechanism for holding the assembly on the leg of the user. The other basic form is one that incorporates the assembly into or on a boot, sock, wet or dry suit, pants or similar device at a location that wraps the assembly around the user's lower leg when in use. The assembly helps move the user's lower leg toward the surface of the water and hold it on the surface of the water to help prevent foot entrapment with rocks, trees or other objects in the water and also helps to prevent the foot or leg from being injured due to contact with underwater and river-surface objects. The assembly has particular value as a safety floatation device for whitewater boating in all its forms and for swimming in strong currents or in rapids. A variation of the assembly may be used as a safety device for traversing or ice-skating on a body of ice.
