Natural World Men's Old Quercia Cotton Shoe
Description
Natural World Old Quercia Men's Cotton Shoe: Vintage Nautical Style with an Eco-Friendly Twist
The Natural World Old Quercia is a men's shoe that takes the classic boat shoe design and reinterprets it in an ecological and sustainable way. The Old finish gives it a natural, worn vintage look from day one, with irregular shades and faded tones that make each pair unique. The 100% organic cotton upper is lightweight, breathable, and gentle on the skin, featuring the classic lace that goes all around the heel in pure nautical style. The 100% natural vulcanized rubber sole—attached to the upper using heat and pressure, without chemical glues—is ultra-flexible, lightweight, and grippy. The removable insoles make cleaning easier and allow for personalized orthotics. Made entirely in Spain with eco-friendly materials and packaged in a recycled cardboard box. The ideal shoe for spring, summer, and outdoor days.
100% Organic Cotton Upper with Old Finish: Breathable, Lightweight, Vintage Look
The 100% organic cotton upper is grown without pesticides or chemical dyes. The Old finish creates a vintage effect with irregular shades and faded tones: each pair has a unique and unrepeatable character, the result of artisan craftsmanship on natural fabrics.
Boat Shoe Design: The Lace Around the Heel
The design echoes the classic boat shoe with the lace that goes all around the heel, an iconic detail that gives a relaxed, casual nautical aesthetic. The low silhouette and lightweight construction make the Old Quercia perfect for warm days.
Vulcanized Natural Rubber Sole: Ultra-Flexible, Lightweight, No Chemical Glues
The 100% natural rubber sole is attached to the upper through the vulcanization process: heat and pressure without chemical glues. The result is a sole with unique softness, ultra-flexible, and lightweight.
Removable Insoles and Machine Washable
The removable insoles facilitate cleaning and hygiene. The entire shoe is machine washable at 30°C.
