A vascular surgeon wrote to me about venous insufficiency.

I felt heavy, swollen, and tired legs.
Ideally, he said up to the thigh, but you will wear these.
My job involves eight hours of standing, as a hotel employee.
I really hadn't felt my legs light for years throughout the workday.
Perfect fit if you get the right size for your foot.
Because they have the toes out, you don't feel discomfort and soon forget you're wearing them.
Be careful when putting them on, don't pull them too hard and stretch them out
(get them below the knee)
and when washing them, do not use hot water and do not dry them in the sun and heat.
I wore them for 7 months every day for work and heavy use.
At some point, you feel that they have lost the intense level of compression they gave at the beginning, so I got a new pair again.
