The Birkenstock Women's Cotton Slub Crew Socks does your feet a world of good by giving you that perfect fit. Birkenstock presents socks with the original Birkenstock Footbed Comfort Sole. Inspired by the original BIRKENSTOCK footbed and integrated into the sock, this anatomically placed plush pad in the outline of the left- and right-hand soles offers an outstanding cushioning effect. The skin-friendly, ultra-soft and GOTS-certified organic cotton is sustainably sourced and offers natural comfort. The pressure-free, highly elasticated ribbed comfort bands offer firm grip without constricting. The flat, hand-looped toe section further boosts the outstanding comfort.
