Recommended compression socks for working adults. I have never used them since purchasing them at the store. The strength of the compression is expressed in "hPa (hectopascals)". The larger the number, the stronger the pressure on the body. When choosing the strength of the compression, it is best to choose based on the value at the "ankle," where swelling is most likely to occur. Please check the photos for the standards. 【Wearing Comfort】 These are comfortable knee-high socks. They have a good feeling of compression and are very popular. - Size: 23-25cm - Color: Black - Type: Women's - Product Name: Compression Socks Since the degree of swelling varies from person to person, choose a product with a compression strength that suits your condition. ※ Please contact me if you do not need the box. ※ There are individual differences in the reduction of swelling. ※ Please understand that sizes may vary slightly depending on the manufacturer. Instant purchase is OK. I am committed to safe and careful transactions. Please feel free to contact me if you have any questions about the product. I am sorry, but I do not offer layaway. #yucci
