Many of the socks in the 1000 Mile range are available in both men’s and ladies fittings, as indicated by the colour coded stitching around the toe seam.
Choose the same size sock as your foot size. If you have narrow feet (D or less for men, B or less for ladies) or are on the border between sizes, you should go down a size. The sock should be a snug fit with no wrinkles.
Pull the sock on carefully to ensure fitted heel and toe box sit correctly on the foot.
