Generally, stovepipe socks use Danny D as the pressure unit, and D represents the thickness of yarn. The greater the Denny number, the better the stovepipe effect (240D 360D 420D respectively). The international practice of medical grade elastic socks is to take millimeter mercury as the pressure unit (therapeutic elastic socks are divided into three levels of pressure, the first level of pressure is suitable for patients with early varicose veins; The secondary pressure is suitable for patients with obvious varicose veins of lower limbs accompanied by leg discomfort and patients after varicose veins operation, and the tertiary pressure is suitable for patients with high swelling of lower limbs, ulcers, blackened and hardened skin, eczema and so on. ) d and mmHg cannot be completely compared.
