Using these Sockwell compression socks is easy. Just put them on like you would any other pair of socks. They're designed to fit comfortably, thanks to the arch support and graduated compression. When it comes to sizing, use the size guide provided based on your shoe size. If you're between sizes, go for the larger one. For washing, you have two options. The easy wash involves turning the socks inside out, machine - washing in warm water, and tumble - drying on low heat. Just make sure not to use bleach as it can damage the fabric. The caring wash is more planet - friendly. Machine - wash in cold water and let them air dry. This will also help keep the socks in good condition for longer.
