Legend Compression Tactical has been doing some great stuff with compression socks, providing mid-calf compression and arch support.
They’re made from a combination of Merino Wool/Nylon/Spandex (percentages depend on style).
Additionally, their Cold -Weather and All-Weather have been certified “FR/No melt, No Drip” & “Flame Resistant” respectively by the United States Air Force.
Legend Compression Tactical will be in Booth #156 (back wall behind the Marine Corps Pavilion).
They are also available from O P Tactical.
