Very interesting. I have a good scar (blister that went too far) from my solid attempt to use my eddy fins for a week last June. I did all kinds of modifications to the strap in an attempt to get a better footpocket fit. Other than the foot pocket, I love the eddy. It can make good power and it's slightly positive... I've been using the scubapro booties.My first test dive with Eddy fin was when I was wearing the scubapro boots. These are probably the slimmest, thinnest boots out there as they are designed to slide into Jet fins foot pocket. It is essentially a sock with a rigid sole. While it fitted my XL-Jets perfectly, it was loose and wobbly inside the XL-Eddy fin. While test diving these in the pool, I noticed that the fit was imperfect, I did not realize just how much power was taken away by the bad fit.
I had been planning to list them on the SB "for sale" section. I'll have to pick up some other booties and try the eddies again before I do that. I'd like to be diving the eddies with a wetsuit and my diverite xt's with a drysuit... if this solves the problem.
Thanks for posting this thread!
