I'm selling these because I bought them to start渓流 trout fishing, but I haven't had the chance to go. They are new and unused. I will also be listing waders and other items, and will offer a discount on shipping if you purchase multiple items. Size: L Color: Black (BK) [Product Description] ● The goal was to be lightweight. ● These are neoprene socks for wet wading. ● The 2.5mm thin neoprene material greatly improves the fit and lightness. ● Water that enters the socks drains from the toes and soles, preventing it from accumulating inside. ● When combined with tube gaiters, they provide a more comfortable wet wading experience than wet gaiters. ● Perfect for those who want to lighten their load for headwater fishing trips. ● We also offer AC-69 Wet Socks, which use thicker 3.5mm neoprene. ● When worn with water shoes for kayak fishing, they prevent foot odor from transferring to the shoes and protect the top of the foot from sunburn. They also prevent sunburn when wearing sandals. [Specifications/Standards] ● Size: L (26-27cm) ● Material: Neoprene / 2.5mm ● Specifications are subject to change without notice. Please understand. ● Manufacturer Part Number: AC-138
