The Men's Mythos Eco Climbing Shoe is basically the same shoe that crack and multi-pitch climbers have come to love for the past generation, but La Sportiva made 95% of it out of eco-friendly materials. The biodegradable leather upper comes from Idro-Perwanger's metal-free tannery to reduce impacts on the environment, and La Sportiva's Eco rubber is 100% recycled.
