WC and Freeride are slightly different designs, it's not just the amount of OMfit. The back cuff of the Freeride is softened via notches placed in the rear support plastic cuff. There may be other differences. Best to ask ZipFit directly.
Leather lining has significantly more grip on your foot. It's hydrophobic leather that, once exposed to some perspiration from your feet, becomes incredibly tacky, thus grabbing onto every part of your foot and leg. There is no getting in or out of a leather lined ZipFit without going racer style. If you want to be able to shove your foot into your boot without removing the liner then you'll need the neoprene lined version. However, I would strongly recommend that you do not try to use a ZipFit liner in this manner. You're bound to screw up the placement of the OMfit by shoving your foot in and out while the liner is in the shell.
Hey all, thanks for the thought you've put into considering ZipFit and your consideration of purchasing. I'm glad you were able to connect with Chris. We discussed this thread at length, and I wanted to chime in with a few points in response to some inquiries.
Freeride: more OMFit cork, traditional forward lean, fluted cuff which is more forgiving. I ski this model in neoprene, I leave it in my Tecnica Cochise 130 and I can get my boot on and off without taking the liner out each time.
World Cup: less OMFit cork, more aggressive forward line, stiffer cuff keeps your stance engaged. I also ski this model in the sidewinder style, which has stiff rubberized plastic the full height of the medial foot (inside of the foot). I also love this liner, and when I am more interested in ripping groomers and skiing en piste terrain, I haven't found a better performing liner.
Neoprene vs. Leather - Sven loves the feel and durability of leather. As some folks have pointed out, the leather can be slightly harder to get in and out of (I like imagining putting on leather pants vs. a neoprene wetsuit - both can be tricky!). The Neoprene also offers slightly more cushion, as the material has more give than the leather.
On the website, we currently have four models listed, some of which you can get in neoprene or leather, others are just available in leather. If you go to your local ski shop, you may find models that are not online. They are still current models, but when we decided to offer ZipFits online (a result of COVID and catching up with the times) we wanted to start small with just the select models featured.
This community is great, our team will follow along here and try to offer insight when it's applicable. Feel free to reach out on social media or through the website. Wishing all of you a winter full of as much skiing as possible. -Jeff
