The black Mares x-stream fins, are they all black or black and clear? Do you also have springs for these fins? Thank you.

Hello, they come in Black and then Black/Black. The Black/Black is the color if you want all black with no white. As for spring straps the standard mares spring straps should work. Hope this helps.

Hello, You have helped me before with a few purchases. I am trying to find some fins to fit my 13 year old son, the problem I have is he wears a 14 shoe. I got a pair of these fins last year and love them. I think possibly if I open them up all the way they might work. Your thoughts.

Hey There!! Yes L/XL will work for him as long as the boots he is using will be soft sole to allow for growth going forward. Hope this helps!! Instructor Bill
