Piercing my tongue
I just bought a new nano and Nike+ kit but I didn’t want the Nike shoes nor did I care for the recent ‘velcro’ hack. Instead of looking like a huge geek with a transmitter in my laces (http://podophile.com/2006/07/14/shoe-hacker-nikeipod-sport-kit-shoe-mod/), I decided to surgically insert the transmitter into my shoe tongue.
Gather up your favorite running shoe. Find an exacto knife or razor blade of sorts and buy a Nike+ kit.
Loosen up your strings and stick out your tongue.
Cut a slit about an inch in length into the backside of the shoe tongue. Try not to cut all the way through to the other side.
Slip in the Nike+ transmitter and push it down into the tongue.
Congratulations! Your ready to run in your favorite pair of shoes.
