Speedo biofuse fins

Comments about SPEEDO Biofuse Training Fins:

I actually never had a chance to try the fins because the sizing is so off. They look like a fine product. Unfortunately, the largest they offer is an XL which turns out to be an 11-12. I scuba dive, so I know larger fins are available. I shouldn't have to cut down a pair of my dive fins for training. You're a large sporting goods company, it's sad that you can't make actually larger sizes available, at least, online.
