Oh my lord; I had no idea there was so much complexity involved! I've just been running in a beaten up pair of regular trainers and the most complex lacing I've done is a double knot haha. Thanks for the link!
when I started running properly (about 14 years ago) I struggled to progress past 2 miles, and couldn't see how I would get any better - didn't help I was running in skate shoes I forget about the lace thing as I only ever have to do it once or twice a year.
