I have been using 5mm Pinnacle wetsuit boots for years and have liked them. As I’ve been shopping for new fins, everything I try with a closed toe ends up with my toes hitting the end of the foot pocket and the rest of the pocket around my feet being a little loose. I dove in XT fins today and enjoyed them except for the looseness. My feet should be the high side for the fin size and springs are tight. I wear a 14 but my feet are narrow and thin. I’m thinking a beefier boot with a thicker sole would solve this and I wouldn’t mind the protection anyway. Any suggestions for me?
