Founded in 1923 in Brescia, a leading industrial city in Italy, "ALTO" is a sock brand with a 100-year history. Their socks are made with the finest materials and techniques, offering exceptional comfort. The three-dimensional form created by traditional hand-linking (hand-sewing) gently envelops the foot with a pleasant compression. Size: 39-42 Generally fits sizes 24cm to 27cm. I wear 25cm and have no problem using them. Reference price: Around 4000 yen. You can find them with a search, and experience the warmth of craftsmanship by artisans. I have other items for sale as well. Thank you for your interest.
