Black surf socks with non-slip grip for a comfortable fit. Designed for cold protection during autumn, winter, and spring. Purchased in spring 2024 at a surf shop in Shonan. Unused. I bought these after being recommended them when I was taking a beginner's surf school course. However, after the school ended, I never had the opportunity to surf on my own, and they've been sitting in storage. I decided to sell them since I didn't use them at all in the spring and summer of 2025. [Purchased at] Shonan [Purchase Price] Around 12,000-15,000 yen. I'm not sure of the exact size of these surf socks, but My foot size is 28.0 cm, and I wear a size 28.5 in Nike. [Size] XL Images added - Color: Black - Features: Non-slip sole Thank you for looking.
