Not a runner and I don't use the socks, but I have and do use the compression sleeves, as does my husband. We purchased them from Tommy Copper and they make a night and day difference. Hubby has poor circulation in his legs anyhow and he wears them when we go on walks, long trips, and plane rides. It's allowed him to go from cramping and swelling to pretty much normal. I use them for added support bc of knee issues as my Physical Therapist recommended them. I never would have thought calf support would impact the knees but something about them helps to stabilize the ligaments going up to the patella.
Tommy Copper makes a whole variety of compression products for different areas of the body. Hubby is now looking into one for the shoulder to help rehab an injury that is taking much longer than it should to heal even with a PT's help.
