Positioning float heels with the heels elevated in the air is considered the best practice to avoid pressure on the heels. This positioning effectively prevents any contact between the heels and the bed surface, which helps reduce the risk of pressure sores, also known as bedsores. By keeping the heels elevated, the weight of the body does not bear down on the heels, thus minimizing the risk of skin breakdown or ulcer formation.

The other positioning methods do not provide the necessary relief from pressure. For instance, having the heels against the bed does not alleviate pressure; rather, it applies direct force to the heel area, which can lead to skin irritation or injury over time. Applying pressure using blankets can inadvertently create friction and impede blood circulation, while extending the legs flat does not necessarily relieve pressure from the heels, thus maintaining the risk of developing pressure-related injuries. Elevating the heels ensures that there is no direct pressure on this vulnerable area, contributing to overall skin health and patient comfort.
