Sole Technologies

  • Xcelerator Sole

    Rottefella Xcelerator racing sole provides increased power transmission in a neutral stance. An extremely light sole, with good torsional stability and increased flexibility in the forefoot.

  • Alfa Flex L-Board

    Alfa Flex system provides excellent toe flexibility as well as extra power when pushing-off. The midsole has a built in arch that makes it extra rigid.

  • Anatomic Insole

    An anatomically designed insole made from a breathable material with good absorbency that keeps your feet warm and dry. The foam construction has cushioning properties that counteracts tired feet and provides excellent comfort. It also features an antibacterial surface that helps prevent odors.

Fit & Support

  • Racing Fit

    A tight and supportive fit that gives full control over your movements. The round heel grip helps to minimize the risk of blisters. Good support and performance when performing at your very best.

  • Asymmetrical Lacing System

    Asymmetrical lacing with an elastic tongue construction that allows the boots to be adapted to the foot.

Other Featues

  • Ankle Race Collar

    A classic-cut, with very good flexibility and total freedom of movement.

  • Gaiter Elastic

    Elastic cuffs at the top of the boot that help keep out snow.

  • Internal Heel Counter

    Heel reinforcements made of plastic that provide better support. An ergonomic and stable heel cap locks the foot in the boot, anchors it to the midsole and reduces the risk of blisters.

  • YKK Zipper

    Alfa uses YKK zippers, the world's best. YKK zippers are lightweight and very durable.

With a ruler, confirm the measurement in centimeters and add additional space according to the list below.
