The On Merino Ultra running socks are designed for demanding runners looking for a secure step and high comfort during trail and road running. Thanks to the combination of merino wool and functional synthetic fibers, they are also suitable for light hiking and active leisure time in variable conditions.

The well-thought-out ergonomic construction supports sensitive areas of the foot, reduces friction, and helps prevent irritation during long performances. The socks sit stably in running shoes, improve ventilation, and provide additional protection in high-stress areas.

  • Merino wool for natural temperature regulation and comfort in various conditions
  • Targeted shock absorption thanks to zonal terry padding in high-stress areas
  • Anti-slip technology for a stable position of the sock in the shoe
  • Ergonomic construction with arch and upper heel support
  • Mesh structure openings for better foot ventilation
  • Ergonomically shaped toe for higher comfort while running
  • Reflective yarn in the hem for better visibility in low-light conditions
  • Suitable for running, light hiking, and leisure activities
  • Sock type: high
  • Material composition: 45% recycled polyamide, 34% merino wool, 13% recycled polyester, 6% elastane, 2% polyester
