M2 Women’s
Note: Available only in Red/Silver

After 90 years of running shoe innovation, Karhu introduces the high-performance M-Series running shoes with ACS technology. This Anotomic Controlling System (ACS) uses a patented horizontal mid-sole element that promotes and supports a more efficient stride.


  • Front Cushion
  • Midsole
  • Carbon Plate
  • Movement Control
  • Arch Support
  • Impact Balance
  • Outsole

Advantages of the ACS system:

  • During the impact phase of the stride, Karhu’s ACS Movement Control and Impact Balance components spread the impact load over the entire heel area without interrupting the runners stride. Using Paromed sensor insoles to measure the impact, Karhu shoes reduced shock absorption up to 34% in the heel.
  • During the rolling phase, the ACS Mid-Sole construction ensures the kinetic forces are not lost allowing the runner to roll over the shoe’s fulcrum point faster. When tested using Force Plates to quantify, the rolling phase of Karhu shoes proved shorter and more balanced and when compared with competitors top running shoes
  • During the exertion phase, Karhu’s unique hourglass front cushioning element better supports the metatarsal bones where pressure is highest and avoids soreness caused by traditional cushioning design.
  • Karhu shoes are not only the fastest rolling from the heel strike through the exertion phase of the stride but can actually lower the runner’s heart rate up to 4 beats per minute and decrease oxygen consumption by 4%.
