Durable as a steel frame

Most Merino socks start great and go threadbare before the season is out.

But then most socks aren't made from a unique blend of Merino wool and polyester sourced from recycled plastic water bottles. The result is a sock construction that's durable as a steel frame.

That's not to say the Merino Thermal Socks are hard to the touch or heavy on the feet. With a double weight knit and flat seam, they are soft, warm, and comfortable under any pair of cycling shoes, no matter the season or terrain ahead.

Features & Specs:

  • Transfer Merino fabric combines wool and recycled polyester for sustainable technical performance
  • 18.5-micron fine Merino Wool Repreve Recycled Polyester created from recycled plastic water bottles
  • Double weight knit for extra warmth
  • Flat toe seam construction provides superior comfort over toes
  • Anatomic arch compression for a performance fit
  • Tall cuff height (21 cm) unisex sizing
  • Fabric made in USA
