Reflector inserts on heels. Lining GORE-TEX "Performance Comfort Footwear" membrane. Reinforcements: Ankle reinforcement, PU shift reinforcement, shin, toe and heel reinforcement. Fastener: Elastic zipper for easier access + wide velcro strap. Insole: Ortholite® footbed with long-term cushioning and high air permeability. Sole: Touring sole with different grip ranges. Gore-Tex® membrane: This fine material has important features such as long-term waterproofing, excellent resistance to the most extreme temperatures and high wear resistance. The special microporous structure of the GORE-TEX fabric, made from expanded PTFE, contains around 1.4 billion microscopic pores per square centimeter. These pores are approximately 20,000 times smaller than a drop of water, but 700 times larger than a molecule of water vapor. While water cannot penetrate the GORE-TEX membrane in liquid form, perspiration (water vapor) can easily evaporate. The result is a comfortable and dry experience.
