Our socks are made with premium materials and superior craftsmanship, and they'll last longer than typical socks.
Depending on how often you use them, how much wear and tear they get, and if you care for them properly, they will generally last for well over a year.
Most importantly, the stated compression levels will last about 6-9 months with proper care (hand wash & air dry).
For best compression performance, we recommend that you look to replace your socks after 6 to 9 months. However, your socks will last well beyond that timeframe!

Compression socks improve blood circulation which helps to rebuild broken down soft tissue. There are many benefits to wearing compression socks including:
