These fins are great for shallow rivers. Living in an area where the closest rivers are rather shallow most of the year and wanting to paddle several days a week, I love these fins, they snap in and out with ease,the screw sets are easy to tighten and loosen, they will take the hits and flex well. It makes it easy to set up for the water that's available. They are a must for every fin kit. I strongly recommend these.

Great little thruster fins for rocky rivers or a looser board on the waves.

Great product good people!

Great so far. Great service

Tighten well... also they can break on heavy stuff so be careful with your lines
