Natural World Men's Old Crabe Cotton Slip-On Shoes
Description
Natural World Old Crabe Men's Organic Cotton Slip-Ons: the classic summer camping shoe made entirely of organic cotton
The Natural World Old Crabe is the men's slip-on that embodies the classic Spanish summer camping shoe, reinterpreted with the Old finish that gives it a natural, worn vintage look from day one. What makes the Old Crabe unique is that it is made entirely of 100% organic cotton: the upper, lining, and insole are all made of organic cotton, for a shoe that is eco-friendly in every detail. The removable cotton insole facilitates cleaning and allows for the insertion of custom orthotics. The vulcanized natural rubber sole — joined to the upper using heat and pressure, without chemical glues — is soft, flexible, and grippy. The slip-on design can be put on in an instant. Entirely vegan, with no animal-derived materials. Made in Spain and packaged in a recycled cardboard box. The ideal shoe for spring, summer, and warm days.
Made entirely of 100% organic cotton: upper, lining, and insole
The Old Crabe is made entirely of 100% organic cotton: the breathable upper, inner lining, and removable insole are all made of organic cotton grown without pesticides or chemical dyes. The Old finish creates a vintage effect with irregular shades and faded tones: each pair has a unique character.
