Do I need better bindings?

I have the Salomon Vendetta bindings and one of the binding straps will get super loose at least once a day and I have to reposition it. This seems not normal? I make sure to tighten the screw and it’s actually pretty hard to loosen the screw when I am readjusting.

Is it because the bindings are lower quality? Should I get better bindings, like Union or Bent?

I am always tightening the binding straps so much that my foot goes numb, because I worry about responsiveness and it loosening. Also I’m still beginner starting to move to intermediate - just started on blues and blue blacks.
