I purchased this at the end of the year, but I no longer need it because I bought a different item during the New Year's sale. I'm selling it below the purchase price, even though it's a loss. 《 Product Description 》 The evolved Sirio 4 series, a tough and lightweight trekking boot for 3 seasons, offering durability, walkability, and improved fit.
