So please, all those of sound mind and strong opinion, tell me why, after a nice long run of no specific distance, the tongue of my left running shoe migrates to the full outboard side of that space between the lace holes and the right one stays perfectly straight?
The left shoe is laced identically to the right shoe and the lace is threaded through the tongue slot that is supposed to hold it in place. The laces are tied with the same tension, best as I can tell.
Is this a problem? Not necessarily although only a specialist might know if some aggregate aggravation is going on there with that.
