This may have been asked before. I did a search, but did not come up with anything obvious. I have been using DUI Rock Boots (Size 7 (women's size 9)) with XL Jet fins & these have done well. I just got a pair of Scubapro drysuit boots & really like the feel & lightweight nature of them. However, the XL Jet Fin seems borderline too large for the Scubapro boots. There is a little slippeage of the foot inside the fin. Not dramatic, but noticeable. How does the Hollis fin (XL, I assume) compare to the Jet fin of the same size? Would this be a better option? Thanks for the info!
