Fins are used to maneuver your float tube. Without fins your float tube is pretty much a toy suitable only for swimming pool activities. The better the fins are, the easier it is to maneuver your float tube and the more comfortable your day on the water will be.
Keeper high-thrust fins are designed to be used with a stocking foot wader. They are roomy open heel fins and can be adjusted to fit most users. They fasten at the heel with an adjustable elastic strap.
Vented design decreases drag on the upstroke and enhances thrust on the downstroke. Easy to use due to their shape, size and material selection: large enough for proper thrust but not too long to decrease maneuverability, flexible enough to decrease the drag somewhat but still stiff enough for proper propulsion.
With these fins you can really enjoy your fishing.
NOTE: Because these fins don't float, it is highly recommendable to attach them to your ankles with short ropes or similar. Even a short distance against waves and wind with a single fin will cause some real pain in your buttocks - literally.
Keeper is a fly fishing tackle brand created by a Finnish tackle manufacturer Vision Group Ltd.
