Uneven Shoelaces

My cousin Peter sent me a link to Ian's Shoelace Site, and I emailed Ian to ask him why, after a week of tying and untying, my shoelaces ends were uneven in length. Here is what he said:

"You asked about the ends of the shoelaces shifting. I'd guess that your shoes are probably laced with either Shoe Shop Lacing or Straight LazyLacing. Both of these do exactly what you described. This is because of theuneven distribution of tension. The solution is to re-lace with any of thesymmetrical lacing methods."

I guess I have to relace my shoes...
