10. Smartwool PhD Run Ultra Light Micro
Wearing wool in the summer may seem counterintuitive, but not when it’s the right kind like the Smartwool PhD Run Ultra Light Micro. The itch-free Merino wool features temperature control, keeping your feet dry in these snug socks that hug arches to create a feel-good fit. A low-profile means you won’t end your runs with a hard-to-hide sock tan.
