These Sockwell men's socks are super easy to use. Just pick the right size according to the size guide using your shoe size. Put them on like any other socks and enjoy the comfortable fit. For easy wash, turn the socks inside out, then you can machine wash them in warm water. Use a low - heat tumble dry setting and never bleach them. If you want to be more eco - friendly and take better care of the socks, machine wash them in cold water and let them air dry. They're diabetic - friendly, so users with diabetes can wear them with confidence. Also, if you're between sizes, remember to size up for a better fit.
