When I tried to get mine, I called Jack Young looking for the new Nacra foot straps. He sent me to the Cat House (Fair Warning: specify "sailing and catamaran" keywords when doing a Google search for The Cat House) and they filled my order. What I received had Magic Marine logos on it but was the same thing. You also might want to check with Brett Moss - he's involved with Magic Marine US now.

LandFall Navigation has them as well HERE
