RiffeFin Keepers

These little things do exactly what they’re made for, keep your fins on. They’re super strong and durable and pretty easy to slap on. I wear an 8 in US women’s and my fins are the Cressi Gara 3000 size EU 40/41 worn with a 3mm sock and the large in these are perfect but dare I say I could probably use the xlarge as well. I did a little research and found the size chart for these so it goes as follows- Medium: EU 30-35 Large: EU 36-41 and X Large: EU 42-47. I just used the EU size of my fins to choose the correct size. I hope this was helpful. Happy finning!

Works well. Dive buddy forgot booties for freediving fins during sandy shore dive and had to wear cotton socks for sand protection. As a result, fins were a bit large and felt loose. Loaned these keepers to them, which ensured that the fins stayed on, and fit more snugly, for 2hr dive.

long lasting quality. they are comfortable and hold the fins on during underwater hockey, which often results in lost fins without finkeepers on

I was disappointed that there wasn't clear sizing information. The LARGE is extremely tight on my feet (men's shoe size 8.5-9).

They run small, but do their job well! (=

Using them with my Beuchat Mundials and they snug up the fit just right.

Works well and priced right

These are great. I ordered the large but they are a little tight so I would suggest buying a size larger.
