I've never used the new style designed for tubing. But with the adjustable instep you have a large variety of footwear from booties to waders w/ boots. I've seen both models at a few different places, namely Sports Chalet and a surf/dive shop in Dana Point. Where do guys live? They are well worth the money, but get fin tethers. As their site states, these fins sink. I liked what I saw at the site (thanks for that heads-up), those $400 fins looked pretty good. Mine are the original ones, I got lucky getting them for $60 with the inserts. I don't know what I would have bought if the manager hadn't offered me the deal ( being a regular customer helped). I'm just glad I did get them, I'll never use another fin.
