Pearl Izumi Merino Thermal Sock

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.
