Editorial Review
U.S. Divers offers a variety of fin styles to meet the needs of water sports enthusiasts whether they're diving, snorkeling, tube fishing, body surfing, or having fun in the pool, and the Twinflex scuba fin is among the best. The Twinflex is distinguished by its dual blade channels, which optimize the water flow and enhance the thrust of the diver. Users will also appreciate the TPR center flex zones, which cup the water efficiently to provide greater underwater power. The fins fit a variety of foot sizes and shapes with ease. U.S. Divers recommends wearing dive boots with the Twinflex fins, which come in M (6 to 9), L (9 to 11), and XL (11 to 13) sizes. The Twinflex is also backed by a two-year limited warranty.

Outstanding! 
2008-08-03
I have been snorkeling for many years with old, old equipment. When my neoprene boots began to shred beyond use, I decided to order these barefoot fins. They are fast, light, flexible, efficient, and allow me to free dive deeper and see much more while I'm down. I spend way too much time in the local lakes since I received them.
Great value for high quality fins. 2008-05-22
I bought these for my fiance during our engagement trip to Kauai a while back. She's a size 8 and the mediums fit her perfectly. They were comfortable and even after wearing them for several hours she did not feel any discomfort and they didn't leave any kind of mark or blister. The design is great and they are definitely very fast in the water.
I like that they are light weight and easy to pack. My fins on the other hand are bulkier and more of a pain to fit in a day pack.
I would definitely recommend these fins for the recreational snorkeler or diver.
Great fins 2008-04-28
Comfortable, great value, satisfied. I went to Caribbean trip with my girlfriend and we used 'em for snorkeling.
Just great fins.
Quality Product! 2008-03-25
How could a winter vacation to the Caribbean be any better? Owning your own snorkel and Fins, to drop in the water anywhere! And these fins practically pay for themselves the first time in the water. They are sturdy and comfortable. Very professional. And with free Shipping they are a BARGAIN!
Good for the money, but could be better

The fins are very comfortable to wear. I am shoe size 8 (medium) and my wife is size 5 (small). My only hesitation is that the fins seem too flexible compared to others we've used. We snorkeled for half a day with these and found them effective, though wished they were a bit stiffer. For the price they are really good.
Amazingly comfortable! 2008-02-08

Very Happy 2008-01-23
I bought 4 pairs for gifts, they fit great I went a little to the large size. They all fit and nobody complained that they hurt after wearing them for awhile snorkling. I may buy a pair for myself!
too wimpy 
2007-11-29
Despite the rave reviews here, I have to cast a different vote. It may work well for leisure snorkelling, but it's too wimpy for regular pool workout.
Very comfortable 2007-10-18
When I first got these I tried them on and was surprised at how
comfortable they were. I didn't have any of that 'rubber biting at
the back of my heel' feel. They fit really well. I'm a size 12, so
I got the 11.5 to 13 size.
As to performance; for the short time I wore them thay seemed more than
adequate. But, not having worn fins for a long time, my calves were
straining with each kick, so I opted to swim without them more than with
them.
I would be perfectly willing to recommend these to anyone considering
them. For the money I thought they were excellent.
Good Buy! 2007-10-02
Great fins, especially for the price. Best deal I could find for swim fins anywhere on the internet.
