The PhD Running Ultra Light Micro is the perfect running sock for mild weather and shorter distances. It is specifically designed for a woman's foot. Thanks to the 4 Degree Elite Fit System and the patent-pending ReliaWool Technology, overall comfort is improved and abrasion in the high density impact zones is reduced.
The 4 Degree Elite Fit System uses two elastics for greater stretch and recovery to keep the sock in place.
The patent-pending ReliaWool Technology in high impact areas provides the longer lasting protection to keep feet comfortable.
