Hagan has a nice lineup of racing and touring bindings. It would be a shame to not ski them because you lost a toe piece. Buy a replacement toe and get back out there. Also you'll probably want some screws since you clearly forgot to mount your bindings to your ski (unless you lost that too?). Below is our huge collection of Hagan toe pieces.
* Note the ZR toe pieces are identical to the ATK SL-R toes, except in color. Screws sold separately.
