XXL
XXXL
These fins are great for propulsion, if you can keep them on. Even my Men that are sizes 9 and 10 could not keep these fins on. The material used to make the part where the heel and ankle sit is too loose.
The foot of the fin is a bit tight. I ordered the mans 7-9 size and wear a womens 8 wide, thought they would be big enough but they are snug across the base of the toes. They are also longer then I expected, but they do make me faster in the water and I can feel the workout in my legs more then without them
Fins are true to size and very wellmade. They are soft and very pliable to swim with. I use them in a pool for weight on my legs.
These fit perfect. They are also great for improving your kick and building leg strength. I would recomend these to anyone.
product performance is very satisfactory. the only problem has been inflammation to the outer sides of feet.
Sizing seems to be much larger than other brands of swim fins. In all other brands of swim fins I have ever used, I wear a Adult 9-11 and normally this is a snug but comfortable fit. (I wear ladies 10.5 shoe size). ClubSwim Rubber fins won't even stay on when I tried them on with thick socks. I'm going to try a 7-9. I have not tried them out because I have to re-order a smaller size..... They appear to be good quality for the money.
