Three pairs of graduated compression socks, 20-30 mmHg, for men and women. The compression is strongest at the ankle and eases as the sock runs up the calf, which is what graduated means and why the fit feels tighter at the bottom than the top.
People generally reach for this level on long flights, on long shifts standing, and after training, because legs feel less tired by the end of the day. If you are choosing compression for a medical reason, that is a conversation for your doctor rather than a product page.
