I bought a pair of these awesome elastic shoelaces and they arrived yesterday and I am rocking them in my Cons, currently.

The idea is that they look just like regular laces-- but no tying and no extra length to dispatch with.

I turned my Jack Purcells into slip on sneakers and they are much more comfortable with the elastic shoelaces than laced regularly as they self-adjust (no part is too tight or too loose).
