I just thoght of this while lookin at the lunocet homepage.I dont know if i improved it or not but its a start.the wierd part on the bars of the foot pocket is ridges to allow a more natural pivot.at least i think it would.the pointy thingys is to keep water from spilling off. lastly the curvy part would be made of something very flexible.im going to put a pic up the minute i find out how.
