For the recreational or club curler it's about controlling the slide. Any variance either way with the toe dip would cause fish tailing. Hard enough to think about line and weight let alone throw out of control.
Also, for less experienced it causes faster push outs and less speed control.
That's why you mainly see experienced curlers use it.

I'm new to curling, and am shopping for a pair of shoes.
Why don't toe dips (aka toe covers) come on all shoes? All top-level curlers I've seen on TV slide on their toes or on their laces. Seems like a toe dip would always be useful.
The only thing I can think of is that without one, shoes need to be replaced more often, which is what manufacturers want.
