The all new Heavy Eddy is an alternate to our neutral bouyancy Eddy that has become one of the best selling fins in diving! Did you need a little extra weight at the feet? Then this one is for you.

The Eddy incorporates all the best characteristics of various scuba diving flippers into one.  It starts with a blade design including ports to allow for better propulsion and a foot pocket that is actually designed to fit a human foot wearing wetsuit or drysuit boots with a comfortable strap.

The spring strap comes adjustable to THREE different positions to adjust the overall tightness of the fit. There are only two sizes of spring, the SM has a small spring, the L, XL, and XXL all use the Large spring set.

The perfect design deserves a perfect material.  The eddy flippers are molded with a XXX material to ensure they're the right stiffness for maximum power, and really comfortable to dive.
Please contact us with any questions.

Recommended Sizing
Sizing depends on the type of boot you're wearing, not your shoe size. If you buy the "SAME SIZE" as you wore in "XX Brand" without reading this part, you WILL get the wrong size.  If you ask us to tell you what size you need based on your old fin that fit saying "I wear a XX Brand size X, what size Eddy do I need?"... we won't know. We don't have every fin on the market to compare our foot pockets to theirs, and won't have.

Customers have found wetsuit boots with a flexible THIN sole in sizes 5-8 fit best in a S/M,    9-11 LG,   11-13 XL, above size 13 the XXL. When wearing wet-suit boots with a thick "sneaker" type sole or a dry suit boot you should go to the next larger size. If in doubt get the next larger size as the spring straps are adjustable for a more custom fit.

  Remember that a normal shoe is sized for the outside dimensions of your foot, which stays pretty consistent. Fins; however, have to be sized to fit the outside of whatever foot protection you choose and vary greatly depending on the brand.

            Chris has a 10.5 D US shoe size and wears the Large eddy fin with wetsuit boots or his dry-suit which has thinner boots (neoprene with a sole).  He wears the XL when wearing wetsuit boots with the sneaker style sole or his dry-suit with larger boots. Landon is the exact same at a 9.5 D, wearing a L when wet, and a XL when diving dry or thick boots. There will be some minor variances depending on the exact boot you wear. That said if you wear a size 12 with a softer sole boot you would be fine in an XL eddy fin.  If rock boots or heavier sole foot covers are worn, you would be better off in an XXL.

If you are diving these with the new Deep6 Neoprene boots - Sizes 6 fits well in the SM, Size 7-8 in the L, and size 9-10 in the XL. These are THICK soled boots.
