I used these fins on a week-long diving trip and they were great.

Very comfortable--no rubbing or blisters. They're flexible (easier to pack) and powerful. They also held up under tight packing and a lot of use.

While some expensive fins may give you more boost, for the price these can't be beat.

RUNS A BIT SMALL: I recommend you buy them slightly larger than you need. I thought I'd need the Large, to size 11, but I'd tried them on in a store and found them too small, so the 11.5-13 were more comfortable. 5 stars

This is by far the best snorkeling fin I have ever used. Most fins cramp your feet within 10 min. but you can snorkel all day in these and they have a lot of snap. A++ 5 stars

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. 5 stars

If you are a snorkeler, then you know what you need and this fin better be on your list of gear! It gives you maximum thrust for your kick. It's got style, comfort and power. It's design makes it easy to carry and it travels well. You can't ask for much more! 4 stars

These fins are great. They are comferatable and are very reliable and flexable. They work great in the water. I own several US diver sets.They are all great. 5 stars
