Review on Maximize Your Swim Performance With FINIS Training Fins by Amy Cook

I usually wear a men's 8.5 shoe, so I ordered the "E" size of these FINIS Zoomers Gold. The "E" is supposed to fit Men's 7.5-8.5. but they were too small for me. I could barely get them on my feet and the fin were way too tight when I did. I know fins are supposed to fit a tad snug so they won't fall off my feet in the pool, but they were just too tight for comfort.So, I had Revain do an exchange for size "F" fins. It was VERY easy to fill out the online info and I had my new fins in 2 days with my Revain Prime. Revain also paid for the return shipping on the first pair that was too tight. The return process could not have been more simple.I got my new Finis Zoomers Gold in 2 days as promised. The Size F fins fit perfect. I recommend if you are at the top end of size range like I am, then order up a size. The E would probably be fine for a size 7.5 (maybe even 8), but was too small for 8.5.Anyway, I wore my new Zoomers to swim my laps today at the YMCA. I swim a mile (freestyle) three times a week. Up until now, I felt like most of my workout had been in my arms/shoulders. I wanted to feel more work in my legs that's why I bought fins. The Zoomers did exactly what I'd hoped for. I swam my mile in about 5+ minutes less than usual with the Zoomers, but I felt a lot more work in my legs. Because I finished a bit early, I added an additional 5 laps with a kickboard using the Zoomers to work my legs more and that helped too. I think I will see significant improvement in my leg strength by using these.I highly recommend these, but order up if you are on the top end of a size range.
