BIRKEN men's outdoor shoes are just the right thing for hiking. They have a light outer layer made from netting and water-repellent polyurethane. The synthetic coating on the heel and toe protects these particularly strained from damage. The soles are made from thermoplastic rubber, a high-quality synthetic rubber that wears down less than other materials. The midsoles contain phylon – an ultralight material that absorbs shocks.- Weight (1/2 pair) size 41: 280 g- Material (upper): mesh, polyurethane Nb- Lining: mesh- Outsole: thermoplasic rubber- Syntetic overlay: heel & toe
