Boy, you really have to pick who you listen to around here ...
"Toe in", move your cleats forward ...
As others have noted,
don't move your cleats forward. In fact, you'll probably be better off moving your cleats as far back as possible (incrementally). But that's a whole other thread.
I'm presuming you are a small person with a 700c wheel road bike. I can't comment on how someone managed to build an MTB w/ toe overlap
Your option is a custom build, perhaps including smaller wheels.
It is also not a big deal as the toe never engages the front wheel under normal riding conditions -- only on slow, tight turns.
I have
one bike with fairly severe toe overlap (even though it has 650b wheels) because of big tyres and mudguards. When I'm on that bike, I just make sure I keep the pedals at 6 O'clock when turning at slow speeds.
