We have the technology. We can stretch them. We fulfilled our number one customer request and developed a way to create our awesome designs on stretchier socks. These babies can stretch up to 21 inches in circumference. Our Tacosaurus socks are now available in our unisex STRETCH-IT size. These dinotastic Tacosauruses needed more stretch to show off their crunchy shell tails and tacolicious fillings. 49% cotton, 49% polyester, 2% spandex. Made in Korea. Approximately fits up to women's shoe size 12 and men's shoe size 13.
