Patagonia R4 Surf Boots These are the sock type. Made with 85% Yulex® natural rubber/15% synthetic rubber (polymer content), neoprene-free, meeting Patagonia's rigorous standards for functionality, durability, warmth, and sustainability. Features a Splatex sole with Tatex rubber touch points for excellent traction and flexibility. The split-toe design allows for easy toe movement and close contact with the board. Retail price: ¥9,000 + tax Worn 3-4 times after being purchased new. I will be selling these as I don't anticipate using them in the future. The size should fit those around 27-28cm. The brushed material makes them warm. #patagonia #surfboots #surfing #R4
