The Loap BIRKEN men’s outdoor shoes are suitable for walks and hikes. Their upper is made from breathable mesh and windproof polyurethane while the toes and heels are protected by overlays to increase their durability. Just think about how many times you trip on something or someone steps on your heel. The outsoles are made from thermoplastic rubber, which resists pressure and peels less. The midsoles features the ultra lightweight and soft Phylon material that is gentle on your joints and absorbs the shocks.
