Question: I'm buying XXL fin. Can anyone help recommend a bootie mm size? Low cut/ high cut? I wear a size 11 shoe. Thank you.
Document: I bought these knock-offs to replace a pair of the originals I bought in 95. I was trying to decide between these old-school and a pair of the lightweight modern ones. I bought these after liking my original pair and went diving with them recently. They worked perfectly. They are indestructible and you can't beat the price. For sizing, I wear a size 11 shoe, and for diving in CA I wear a hard sole bootie and the XXL fin fit perfectly.
If you are looking for a solid (and heavy) fin that will survive any amount of abuse, this is probably what you are looking for. If you are looking for something lightweight and attractive, these are not for you.FYI: I ordered the XXL since I wear size US15 shoes (with a 14.5 foot). They are definitely sized right (even with room to spare).
I have not used them in open water yet but they seem like a pretty solid, essential set of fins. They're very basic but that's all you need. No flashy colors or anything which is great for me because most of what I do is salvage diving. To give you an idea for sizing, I wear a size 9 bootie with a VERY thick boot style sole. I got a size XL fin and they fit over the boots snugly.
The fins are exactly as described and in great condition. I have a men's size 13 shoe and ordered an XXL based on the sizing chart provided. I did not have booties at the time but I can almost guarantee you that if I had a size 15 shoe and 8mm booties, I still don't think those fins would have fit. The XXL fins were seriously gigantic.
To make it short and simple, this company sent me the wrong size fins which I called to verify sizes prior to ordering and they said the XXL would fit a US size 10-11. Once received the fins were way too large but I tested them in the water anyways to ensure that they were, and of course they were. I sent the fins back to the company in which I paid 10$ to ship back to the company for an exchange after receiving the go ahead to do so from them.
When I got mine I was surprised by the quality of the fins. Highly recommend these to anyone who is looking for a good set of fins for a good value. These are very durable and I love the feel of them.
I would either recommend going down one size if you plan on using just the sock, or following the charts but using a 5mm+ thick neoprene sock with a sole and toe wrap around. I don't do that because it was more expensive but whatever.Also don't try to buy a replacement buckle/clip on  system for the straps. It won't fit.
I wear these fins with the 2-3 mm sock thats also sold on amazon and it fits PERFECTLY. Its not too short that the strap hits my ankle. Also the straps on these fins are brand new so I dont see them snapping anytime soon. But I will be looking around for a back up pair of straps that are identical to the ones they came with if it does happen.
Ill be in the navy special warfare program in a few months after this summer when i ship. I was looking for a way to get used to finning before I left but I didn't want to spend a great deal of money for something I would only need to use for a few months. These fins fit the bill almost perfectly. The only thing I did wrong when ordering was the sizing. I have a size 13 foot, so to I ordered an XXL.
These fins offer good control and I was able to turn in place with using one fin and swim backwards using the back kick technique. As with all fins, proper kick technique will go a long way. These fins are negatively buoyant and will sink if you let them go. They are just slightly lighter than scubapro jetfins of the same size, and they are very close in stiffness when it comes to flexibility of the fin.As of right now, I have only used these in the pool on scuba.
Answer: yes
