  • Alfa Air™

    Alfa Air™ consists of two laminated layers. The outer material is perforated microfiber: maintenance free and extremely durable. The second layer can be varied to provide product specific features, such as added insulation, elasticity or breathability.

  • GORE-TEX® Surround

    The unique Surround™ technology combines 100 % waterproofness and breathability in a very innovative way, and is used on our low and mid A/P/S hiking shoes. By including a breathable system with air ducts underneath the foot, it is designed to maximize end-use comfort in moderate to warm conditions and during high activity levels. 

    Please note that the open structure allows water to penetrate through the air ducts on the side, in example if you step in water or a swamp. Many will experience this as a bit unusual / strange feeling, when your feet are cooled by the water. This does not impact the shoes' ability to keep your feet dry - the waterproof GORE-TEX® inner sock ensure it. The Surround™ technology can even be used to cool your feet on purpose on a hot summer without getting wet.

Sole Technologies

  • Anatomic Insole

    An anatomically crafted insole that keeps your feet dry and comfortable in breathable materials with great absorption. The foam construction provides shock absorption, comfort and relief for tired feet. The antibacterial surface also helps prevents odor.

  • Lightweight EVA Midsole

    Extremely lightweight and shock absorbent.

  • Surround L-Board

    A ventilating L-board with embedded air canals underneath the foot. The system will quickly wick away sweat and heat from the foot and transport it out of the shoe.

  • Vibram® Grip APS

    Grip APS is a custom-made sole, developed through Alfa's cooperation with Vibram®. The cleating is self-cleaning and provides optimum grip in our Hiking Mid and Hiking Low boots. Defined knobs provide great traction in uneven terrain and the defined sole edge ensures excellent grip on rocky surfaces. The heel definition increases downhill safety.

Fit & Support

  • Double Lock System

    A lacing system with four lock hooks on each boot that provide the opportunity to independently tighten or loosen over the instep and ankle, for an individually adjusted fit.

  • Standard-last Hiking mid and low

    A regular and stable fit provides complete control, while the round heel shape reduces the risk of blisters.

Other Featues

  • Complete Protection

    Reinforcement around the complete lower part adds durability and increases life span.

  • Hang Up

    Provides the opportunity to easily hook together or hang up the boots.

  • Mini Gaiter

    A elastic gaiter at the collar is a great feature that keeps out debris.

  • Taped Seams

    Adhesive film applied to seams for added water resistance.

  • Laces

    Alfa laces are impregnated to prevent water absorption.

Size chart

Size chart

Place a paper close to the wall and with bare feet place the foot on the paper, with your heel to the wall. Since it is important to stand up straight, preferably have someone help you draw a line in front of the longest toe. Remember to measure both feet as they might not be identical. With a ruler, confirm the measurement in centimeters and add additional space according to the list below.


Hunting and Hiking

  • Hiking Low and Hiking Mid approx. add 1 cm.
  • Mountain, Hunting and Winter boots add approx. 1.5 cm.

Skiing boots

  • Racing add approx. 1 cm.
  • Backcountry, Touring and Expedition add approx. 1.5 cm


  • Low and Mid add approx. 1 cm.
  • High add approx. 1.5 cm.
