Fizik brings a high-end women´s triathlon shoe created with the concept of using the best materials in the correct application to meet the requirements of professional female athletes. The K1 Donna is equipped with a clever construction of neoprene coupled with perforated neoprene on the forefoot, to give increased flexibility and breathability. Weather resistant sail cloth Velcro straps and a loop on the back provide quick and easy take on and off. The ultra stiff Carbon sole and comfortable 3D-Flex cycling moldable insole make the K1 Donna the perfect high-end and lightweight pro women´s shoe. Of course it is completely handmade in Italy.

Key Features:

  • Breathable neoprene upper: ideal for putting on/taking off in transition, adapts to foot's shape.
  • 3D Flex Outsole – T700 carbon, Tepex™ heel cup and polyurethane Mobius Rail™
