Despite the uncertainty of its origin, this style shoe was inspired by the Far East's living fossil, continuning the preservation and uniqueness that the tree carries with it. The pull-grain leather upper is treated with river stones to temper the hide naturally, which gives an attractive rustic look but softened until optimal comfort is reached. Microfibra lining absorbs humidity with its antibacterial and anti-odor treatment. Insoles are breathable using recycled carbon that optimizes shock-absorption. The exclusive frog shock system gives an additional cushion within the insole that absorbs the impact of the heel. Outsoles are made of 100% natural rubber, achieving shoe flexibility and durability.
