Alternative to Nike shoes:
While I was researching for new shoes, I found this holder for my Nike+ chip. This holder is made by a company called lacelid. You can find them at http://www.lacelid.com/. I am thinking to give it a try. I will post more information on it when I get one with my new shoes.
