After quite a bit of use, I can say that they are very good for their price. The depth is relative. For surface use, they might tire you a bit due to their size and they make a lot of noise (so don't expect to see much below if you make noise on the surface).
Once worn and broken in, I have the impression they get better. They don't stretch out, don't get confused, the fin just softens slightly and that's a good thing.
Overall, they are value for money and Greek-made.
They were also worn without socks, no problem at all.

It's just fine for surface swimming and for diving (I reach up to 7-8 meters, I guess it will be just fine for more as well). I made the mistake of getting socks; the 3mm ones don't fit with size 45.5 in the shoe and 44-46 in the fin. The pleasant surprise was that they're perfectly wearable on their own for snorkeling and diving. I wonder why they say socks are mandatory...

They are indeed beautiful frog sandals, I have not tried them in the sea yet. They look sturdy and for a beginner up to 10 meters who wants to touch rocks, I think it is the best choice. I will come back when I try them

Very comfortable and relaxing sandal! One of the top in its category, of course it's not for rough terrain!! It's perfect up to ten meters depth, very durable and the definition of value for money.

It is of good quality, however, those who do not know anything about diving should keep in mind. It will not help those who want it for surface swimming. In other words, its use helps those who want to dive to significant depths.

A VFM sandal for free diving and spearfishing, you won't find a cheaper and equally durable one. The material is sturdy and withstands the test of time, it has nothing to envy from plastic sandals of the same category that you find at double or even triple the price.

Very good for a plastic sandal.
A decent sandal if you don't go down to the depths.
Nice color and durable material
