The arena duel fins are a black design perfect for pool training, diving, and snorkeling. They are USA size 6.5-7.5, EU size 38-39. As you can see in the photos, there are some areas that have turned white, but this is due to the nature of the material and does not affect the basic performance at all, in my experience using them in the pool. However, please refrain from purchasing if you are overly concerned about this. - Brand: arena - Model: duel - Color: Black Thank you for viewing.
