Description
International Fin Shipping Fee reduced to $10 for a limited time!
The SPEED 400 fins have been developed for those who would like to fulfill the 400 long-distance with an even, high pace.
This type is also suggested for those who swim long-distance series during the training.
They are softer than the speed ones preventing you from acidosis during the event of the competition.
They are the ultimate travel fin, sitting easily inside a standard sized backpack.
The strap back design allows two 'modes' of use. When worn upside down, the fins push loads more water! Much more powerful.
Available in three sizes. Dive booties are recommended for improving comfortability or loose fits. Discounted medium US Divers Mesh bags also available with purchase, they are a great fit!
