Casual Stem sneaker is not only comfortable and cool summer sneaker, it's also a sustainable choice. The upper material is completely made from seaweed fiber, so it is renewable and plant-based. Knit in seamless sock construction, for ultimate comfort. Soft material is very breathable, and sneakers washable, even in machine, in low temperature. Thick but light Phylon midsole is shock absorbing and flexible, thanks to strobel-construction. Removable Comfort+ insole is antibacterial and soft for extra comfort.
