Flow bindings are not necessarily easier to step into, even coming right off the chair - and definitely not easy to get into in powder. With that said, they might be the most comfortable binding I've ever ridden. I was highly dubious about them, but decided to go out on a limb and bought them for my second board (other board has Bent Metal). What I like about Flow is that they provide the lock-down power of strap bindings but without any pressure points.
I've got an old pair of Flows, and have been away from snowboarding for several years. But I see that they've upgraded the design to include ratchets - I tried to find ratchets to mod my bindings, but after getting them set up correctly I gave up on the mod. The new bindings look to be quite slimmed down from the original design, though I hope that doesn't come at the price of comfort - the bases look great but the strap doesn't look as robust. Still, I'd love to try a new pair.
