I have the Flight Mini for Ambidextrous reasons, these extenders game me the extra support. Now I have the lock in feel of regular flight fins, but I have the ability to switch easily. Or have friends that right different from me ride my board. Which is great because I ride Goofy style, so friends can hop on and get the lock in feel too. Would buy another set for my future Onewheel, except that will be a full flight fin combo
