GULL yellow fins, size S, perfect for diving. For reference, I used these fins: Height: 168cm, Weight: 52kg, Shoe size: 25-26cm, Slender build. Purchased around 2019. Diving trips: Approximately 6 times. Thank you. - Brand: GULL - Color: Yellow Here's a description of the product: -------- These strap fins are ideal for scuba diving, specifically designed for drysuits, focusing on weight, balance, and propulsion. The heavier sole distributes weight, lowering the center of gravity compared to ankle weights. This provides more stable underwater balance. *Equivalent to using 0.5kg ankle weights. The large boot pocket makes them easier to put on and take off. Because ankle weights are unnecessary, the fins themselves have weight. Therefore, these fins are recommended for divers who are confident in their leg strength and seek greater propulsion. Thank you for viewing.
