We study the existence of

foliations adapted to Reeb flows on the tight

-sphere. These foliations admit precisely three binding orbits whose Conley-Zehnder indices are

, respectively. All regular leaves are disks and annuli asymptotic to the binding orbits. Our main results provide sufficient conditions for the existence of
