  • Alfa Air™

    Alfa Air™ consists of laminated layers. The outer material is perforated microfiber; which is maintenance free, well breathable and extremely durable. The other layers can be varied to provide product specific features, such as added insulation, elasticity or breathability.

    The great breathability offered by the Alfa Air™ uppers ensures comfortable feet even in warmer days. Perfect 3-season shoes, well suited for outdoor activities from late spring to early autumn.

  • GORE-TEX Extended Comfort

    With highly breathable, hydrophobic materials, the Extended Comfort technology keeps water from penetrating the shoe while sweat evaporates from the inside. It is suitable for moderate to warm conditions and during higher activity levels. 100 % waterproof and highly breathable, it offers a dry and comfortable environment in higher temperatures and activity levels. The Extended Comfort technology is mainly to be found in a selection of Alfa's Hiking Low and Mid boots.

Sole Technologies

  • Lightweight EVA Midsole

    Shock absorbing midsole with low specific weight, where cushioning and stability are adapted to the shoe’s intended field of application.

  • Stabilizing L-Board

    Great technical features provides stability throughout the product's life span.

  • 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.

Fit & Support

  • S-last/Narrow Mountain and Hiking

    Narrow width 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 of the show to improve durability and increase the shoes life span.

  • Crampon Compatibility

    Groove for crampons. Compatible with hybrid and strap-on systems.

  • Double Lock System

    In order to adapt the boot individually, ALFA has chosen to use two sets of locking hooks. This way you can lock the laces over the foot’s brigde, adjust the laces over the ankle's bending point, and then tighten and lock before tightening the shaft itself.

  • Enter Ease

    Construction that makes it easier to put on the shoe.

  • 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.

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.
