Soccer Cleat Experts!?

Hi, I just got a decent soccer cleat size 9.5. however i was born with 6 toes on my right foot but had a surgery when i was a kid and now my right foot is really wide. therefore, i always buy bigger sized shoes so my right foot is comfortable. anyways my question is when i wear these soccer cleats, my left foot fits perfectly but my right one is very tight and uncomfortable and there is also like an inch space from my big toe and the tip of the shoes. how much space are you suppose to have between your big toe and the tip of the shoes? i heard it should have almost no space. so should i go exchange to like size 9? but i m scared that its gonna be even more tight on my right foot... help me please Thanks!
