I just bought a new drysuit that is going to be custom cut from a LDS. I now need new fins because the rubber boots will not fit my old fins. I tried on SP nova's and jetmax and found the XL fit with the boots. The shop did not have any jets to try. I would like to know is the fit the same so I can buy online. My suit is going to take a month, so I will bot be able to try on new fins before then with the new boots (size 11).
