Intimate Service: We provide 4XL, 5XL, 6XL, 7XL plus size compression socks for people with large calves. Please choose according to the size chart provided in the product picture. Best Maintenance: The best time to wear compression socks is when you get up in the morning, because the blood circulation is the most unblocked and the swelling has not yet begun or the leg is lifted for 5-10 minutes before putting on the compression socks. This action can prevent blood from returning. The effect of this action is even more significant for long-term standing people. Cleaning and Maintenance 1. Hand wash or machine wash. The best water temperature for washing compression socks is within 86℉. Use mild, delicate detergent to clean. Place compression socks in the shade to dry naturally. Can use a dryer to dry, but do not turn on any heat source for drying. 2. Do not dry clean or iron. Do not dry or bake them in the sun or artificial heat sources. 3. Spare several pairs of wide calf compression socks for replacement, which can extend the life of the compression socks.Matters Needing Attention: 1. Before wearing compression socks, pay attention to the acceptable pressure of the legs, and do not blindly pursue high pressure. Wearing inappropriate socks for a long time will cause leg swelling, red pimples and pruritus. 2. Use with caution for severe leg skin disease and leg joint inflammation. 3. Before wearing compression socks, pay attention not to scratch the compression socks with nails, and pay attention to the buckle and zipper of shoes or boots to avoid scratching the compression socks.
