SONIC PRO
Hot, sweaty feet want to breathe, and the SONIC PRO sock made from a blend of Microlon® and polypropylene pulls moisture away from your feet. Great ventilation and ample cushioning from a lightweight sock, SONIC PRO gives sweat hogs a break.
Soft Feel
Microlon® feels incredibly soft, even as you push through the last, longest miles of the day.
Moisture management
Polypropylene pulls sweat away from your feet faster than you can say polypropylene.
Cushioning
A little more cushioning in the sock helps make the ride of the shoe that much more comfortable on rough terrain.

- Place a sheet of paper on the floor and against a wall.
- Stand on the sheet of paper with your foot perpendicular to the wall and your heel against the wall.
- Use a pen to draw a line just in front of your big toe. Repeat for both feet and take the longer distance to determine your size.
- Then use a ruler to measure the distance between the wall and the line you drew to find your size.
