 Scuba booties are like neoprene socks. Some have a zipper up the side and hard bottoms so you can walk over rocks and other hard surfaces. They protect your feet from burns and cuts when walking on rocks, rough decks and hot pavement. If you are a cold water scuba diver they will help keep you feet warm. ;-)
Booties can also prevent blisters from the heel strap of your fins rubbing directly against your heel when walking and swimming. |

 The math is surprising. Every extra Kg of downward force requires a Kg of upward force to balance it. But because an air bubble expands and contracts with depth changes, you have to be constantly adding air to the bubble or subtracting it to keep its volume the same . 2Kg extra of lead, which is common, means a bubble four times as big and requires four times as much dancing on the power inflator to keep a constant volume. On the other hand, less extra weight means a smaller bubble, which has less effect on your buoyancy when it grows or shrinks.
