The soft, natural rubber material ensures comfort during prolonged use, which is a significant advantage for extended training sessions. Additionally, the fins are designed with a regular fit, making them easy to pull on and off. However, the long blades might be less suitable for swimmers looking for more flexibility and maneuverability.
