I have had my arena for 30 years and I allow free lunging in the arena. We do not use it for turn out. It has not damaged the footing at all. I do ask the boarders to rake the area where their horses have rolled. I have spruce boards for kick boards and have three boards with holes that happened when a horse that was ridden kicked out. At some point I will replace those boards.
When it is cold in the winter I allow my own horses have a good run before I get on them. When the footing is hard and frozen outside they aren’t able to run the sillies off. I prefer they do that without me on their backs.
