Our older ARC 22 (12' beam) has a three piece tramp with two sets of lacing, 1' inboard of, and parallel to the inner gunnels. Great for your heel, the hiking straps are right there as well.
I like it. We also have hiking straps 1' either side of centerline on the forward half of the tramp, so that crew can be secure forward and inboard in lighter air.
