Enables the person to move around while wearing.
These silicon socks look a bit odd at first glance but they work great and best of all, any lotions and oily creams are contained on the inside so you can walk around. They are very soft. I haven't had them long so I can't comment on durability, but they are not made of lightweight material.

Does the job but dangerous to walk with!
Does the job but dangerous to walk with: foot is sliding inside the sock if the foot was treated with cream or lotion prior. It is uncomfortable to sleep with but a necessary hurdle to heal your heels!
