Query: Tight & stiff

I wear a 10 1/2 EEEE in New Balance. Purchased the 11-13 size. The fins are too narrow, bind my feet on the side, and the opening for the toes constrict my toes to discomfort. Stiff in the blade is good, but in the foot section has caused blisters. Rather than taping, I now wear running socks inside them to prevent the blisters where the fins bind and rub. As I lap swim at least 2 miles in 1 hour per day, the on and off is a hassle. Wore Churchills for 30 years, but the heel strap wouldn't take any more repairs. I would have been better off paying twice+ as much and getting a known product. These might be OK for someone with fairly narrow feet, wearing them once, infrequently, or for a short period of time, but not me. As I'm tight, I'll struggle with my mistake. Ed P.
