Natural World Men's Astun Suede Sneakers
Description
Natural World Astun Men's Suede Sneaker: chrome-free tanning, soft fit and essential design
The Natural World Astun is the men's sneaker in genuine chrome-free suede that combines everyday comfort, essential design, and a more responsible tanning choice. Chrome-free tanning is a leather processing method that eliminates the use of chrome — one of the most impactful substances in traditional leather processing — resulting in very soft, breathable leather that is gentler on the skin and the environment. The clean design and modern lines make the Astun extremely versatile and easy to match. The rubber sole is flexible and grippy, while the removable insole facilitates cleaning and allows for custom orthotics. Designed in Spain with attention to materials and environmental respect. A perfect men's model for the city, work, travel, and leisure in every season.
Chrome-free suede: soft, breathable, more responsible
The chrome-free suede upper is the heart of the Astun. Chrome-free tanning is an innovative process that replaces traditional chrome with alternative tanning agents, significantly reducing the environmental impact of processing. The result is leather with exceptional softness, highly breathable and flexible, which adapts to the shape of the foot, offering a natural and comfortable fit from the first wear.
Rubber sole: flexible, grippy, durable
The rubber sole is flexible, lightweight, and non-slip, offering secure grip on any surface. The robust construction ensures durability even with intensive daily use.
Removable insole: practicality and hygiene
The removable insole facilitates cleaning and hygiene of the shoe, and allows for the insertion of personalized orthopedic insoles for custom comfort.
