After a season of use, I have good and bad things to say about the REV's. First they are cheaper than just about any other hold. You can get them with or without enclosures which is nice. They're roomy but not roomy enough. I have a size 9 shoe so very small and I was forced to use light padding on top and light/medium padding on the bottom just so I could use wrestling shoes with no socks. So that means that there is a very noticeable corner on the top of the hold that digs into my feet (it looks round but your feet will tell you otherwise). The holds have a section dug out for your ankles but it's not deep enough and all it does is wear the hair off your ankle...interesting trying to explain that to all your friends. The last thing I've noticed is that, even with enclosures, I can't keep my feet in those holds. Since it's a full foot enclosure, your ankle can't bend when you're all the way in the hold so you're forced to back out a bit and then you pull up with your feet and you unexpectedly pop out in mid air and that has caused all of my injuries.
That is one thing I noticed.
My take, a foothold should fit like a glove (or shoe!!!!!!!!), yes, you can use padding to custom form them to your foot, but that is a whole lot of work. I started out with the 24/7 2002 Bindings, I loved them, until I road in the surf, they tore my ankles up, would flat rub the skin off. Flat water, no problems. I got some WCF's for my current hull. WOW, what a difference. I could stand to tighten them up some, but I have only had my feet come out just a few times, usually only one foot comes loose during a roll, never had the rag doll effect that you see many people have.
I would seriously consider the WCF Holds.
