I just purchased the Finis Competitor XXL model. And they're way too narrow for my feet! Luckily I purchase them on Amazon Prime and they're going back next week. I've actually subsequently read a lot of negative press on that particular brand. I would greatly appreciate any recommendations on a monofin that would accommodate a size 13 EE shoe size. I can't find any WIDTH info on any of the websites. I'm going nuts here. 100 and 200 butterfly were my events in college and consider myself a very strong swimmer. I'm hoping to get specific model and size recommendations. Thanks in advance!
