Has it ever affected your balance? (Or mobility/locomotion at all?) I'm guessing that since you've always had them and both feet being equal that you just didn't have any other basis for comparison. 
  The comment you made about being an athlete points to it not being an issue of any kind.

  I ask because toes are huge for our balance as bipeds. Some who have lost toes say there balance was affected somewhat. Was curious if there was anything similar with a "fused" toe.

At the very least....one less crack to clean. So that's good in my book lol.
