CETMA COMPOSITES fins and monofins are for use in water only. Under no circumstances must the fins be worn and used outside the water.
Remember that the fins cannot break during the simple kicking, however during the kicking an already existing damage, perhaps caused by improper use previously, could propagate. For this reason, we recommend that you always check the fins before going in the water. If you notice even minimal damage, or any alteration of the product, we strongly recommend to NOT use the fins. Since carbon fiber is a electricity conductor , it is not recommended for use during thunderstorms with lightning.
