The German compression knitwear store "Bauerfiend". A pleasant girl consultant of the department explained everything clearly on the use and care of the product, clearly showed how to wear stockings correctly. I recommend that you carefully read the instructions for use. The silicone tape should be wiped with a damp cloth from the inside once a day, in the morning, as stockings were put on, so that it holds well and does not slip. Buy special gloves for stockings to distribute stockings along the leg, a really useful thing.
