Problue Fin Keepers Features:

• The Problue fin grippers are a great accessory to help create a firmer more secure fit for a closed heel fin.
• The fin grips are made from durable flexible rubber and are ideal for Snorkelling, Spearfishing, Bodyboarding or any environment where you are using fins in turbulent water.
• They are very good for Spearos and freedivers wearing diving socks and diving to depth, as socks will compress at depth which may have an effect on the fit of the fins and the fin grippers will account for this.

They are available in 3 sizes: S, M, L
