Thank you for viewing! This is a brand new, unused Mares Avanti Quattro Power SF. * Ideal for both scuba diving and freediving * High-power & highly efficient full-foot fins * Target audience: Intermediate users These fins can perform all-around. They deliver maximum power and propulsion for snorkeling and freediving at resorts. This is a long blade model for professionals. I bought them because they looked cool, but they were too heavy, so I'm reluctantly selling them from my home without using them. They are unused. I think I bought them for around 27,000 yen. * Size 42-43 (26-26.5) \* The numbers in parentheses are boot sizes. If you are looking for full-foot fins like GULL, gull products, Super Mew, or Warp Fins, please consider these as well. :)
