Smartwool

PhD Trail Running Mini Sock

A lot goes on in your shoe when you trail-run for miles. The Smartwool PhD Trail Running Mini Sock is ready for all of it—the heat, the sweating, the repeated impact. Wool-on-Wool technology reduces shock and abrasion by padding the heel and forefoot with durable yarn, mesh zones on the top of the sock let hot air escape, and the wool transfers moisture quickly and fights odor. The ankle-height cuff works well for super hot days.
