The Womens Fusion Anklet Sock from 1000 Mile still combines the comfort & protection that comes from a padded sock with the 1000 Mile Double Layer System for reduced friction & blister protection. The padded zone on the heel which helps to protect the Achilles tendon has been extended around the ankle & they have re-shaped the padding on the toe & ball of foot areas to make it even more comfortable. With added ventilation zones on the top of the foot area to increase breathability & help keep the feet feeling cool during wear. This sock is knitted to an ankle length for those who prefer a shorter sock.
