The 1000 Mile 3 Season Performance ladies socks guarantee reduced irritation & rubbing thanks to a flat toe seam & offer arch & top ventilation to keep your feet dry & cool when walking or running. There is a tear-drop shaped cushioned zone ensuring more coverage for ankle bone & a comfortable feel & the socks provide a supportive fit due to arch bracing. These lightweight socks keep your feet warm during long, brisk walks & feature padded comfort zones in the toe, ball & upper mid-foot to deliver a good level of cushioning. They are machine washable at 30 degrees (no tumble dry).
