Put the warmest sock in the PEARL IZUMI range on your feet this season with these PI MERINO WOOL THERMAL SOCKS. They are fluffy-slipper warm thanks to being twice as thick as most other socks and they feature anatomic arch compression and a flat seam toe for all-day comfort in snug cycling shoes.

Soft against the skin these 21cm tall cuff PEARL IZUMI THERMAL MERINO WOOL SOCKS benefit from responsibly sourced 18.5-micron Merino wool for superior moisture transfer and thermal regulation working in conjunction with recycled Polyester to make them as durable as a steel frame.

In the age of recycle awareness, it's great to see that the high-performance, moisture-wicking REPREVE Polyester technical fabric used in these socks is made with yarns created from recycled plastic water bottles. This will certainly make a great talking point at rest breaks.
