When the Nike+iPod Sport Kit was announced, I was really excited about being able to track my running progress with my iPod nano. I was not excited, however, by the thought of having to switch to Nike running shoes to use it. The notch that’s cut into Nike’s new shoes for the transmitter is a brilliant idea, but I don’t want to sacrifice the support and comfort I get from my trusty Saucony Hurricanes. Since the Sport Kit transmitter is just an accelerometer, I figured there had to be an easy way to attach it to my shoe laces.

Well, my Nike+iPod kit arrived yesterday and without wasting any time, I tucked the transmitter under my laces and jumped on the treadmill. Everything seemed to work just fine, and the transmitter hardly shifted during my 10 minute trial run. But I knew that If I wanted to run outdoors for long distances, I’d need to come up with a more secure solution.

After 17 seconds of brainstorming, it hit me: Velcro. This morning I dug through my wife’s sewing kit and found a strip of velcro with adhesive backing, a needle and some thread.

First, I placed the transmitter under my laces near the toe and marked the position that I wanted to attach the transmitter, making sure it was underneath a cross in the lace.

I then cut a small piece of velcro and attached the “hard” side to the back of the transmitter, being careful not to cover the sleep button.

Next, I stuck the “soft” side of the velcro onto the tongue of my shoe where I had previously marked.

Using the needle and thread, I sewed a few stitches through the velcro and the tongue of my shoe, securing them together. It can be tricky to push the needle through the layers of fabric and the velcro’s adhesive, be careful. Six to eight stitches should do.

Lastly, I attached the transmitter to the shoe and laced it back up.

The whole process took about 10 minutes (including taking the pictures) and doesn’t permanently damage the shoe.

Early results seem to indicate that having the transmitter under the laces rather than inside the shoe does not affect the accuracy of the device, but I’ll run some tests over the weekend. EDIT: My results are posted here.

Update Sunday, July 16, 2006:
Several people across the Interweb have suggested that I’ll come home from a run one day to discover that my transmitter is gone, having fallen out of my shoe along the route. There are two reasons why I’m not so worried:

1) I’ve run a total of 15 miles over three days and the transmitter is still securely stuck to my shoe. If you apply the velcro properly and make sure that it is tucked under your laces, you should have no problems.

2) If the transmitter does fall out of your shoe while you’re running, the iPod nano will stop recording any activity. After two minutes, the voice will announce “Activity stopped. Press the center button to resume your workout.” If I ever hear this announcement while I’m running, I’ll check my shoe. If the transmitter is gone, I know it’s exactly two minutes behind me.

Now, if the transmitter falls out and gets stuck to a piece of gum on another runner’s shoe, I guess I’m S.O.L.

Update Sunday, July 25, 2006:
I’ve posted some additional tips here to help you make sure that you don’t inadvertently lose your transmitter when using the Nike+iPod kit with your own running shoes.

Update Saturday, December 30, 2006:
I’m happy to report that after 5 months, I’m still running with the sensor attached to my shoe as described above. No problems. But since I first posted this, several commercial products designed for attaching the sensor to your shoe have been introduced. Be sure to take a look at my Nike+iPod Shoe Hack and Sensor Accessory Round-Up to see the most popular ones. I’ve also written a Nike+iPod FAQ to help answer other general questions about the Sport Kit. Here’s wishing you many happy miles in 2007.

  14. Madi says:

    About the Nike+, I have Nikes but I don’t like to run long distances in them. I like to run in my Brooks. So you think that I can velcro the chip to my Brooks? Please respond before I buy it!! Yikes!

    I bought a purpose nmade pouch that attaches the laces…may have cost me a few more $$$ than doing it myself but saves the messing about!

  16. Madi says:

    I really hope that works. I think I’m going to try to run in my Nikes to see if I like to run in them. If not, I will do something to my brooks! Thanks for the tip!

    Yday I bought my first Nike Air Running shoe (I had been using Reebok till now) and now I am planning to buy Nike+ sports kit.

    But I have a very basic problem to solve. While running, usually mt earphone slip away due to sweat. I have tried almost all kinds/shapes of earphone even at the cost of quality of sound but in vein.

    Has anyone faced this problem before? Which earphone do you guys use in Gym or outdoor running?


  21. Podophile says:

    Hi Shrini – I had a similar problem with headphones. I posted about my soulution here: The Best Headphones For Running

    There are many good suggestions in the comments of the article as well.

  22. Andy says:

    Hi, I have bought one of those neoprene “socks” for my nike+ sportsband sensor and mounted it on the left foot in between the laces (at the base) and have been running lots with it. I thought this was the business until I started to map my runs… and found that it is quite inaccurate. For example I have just completed a 6.30mile run in 48 mins and when I mapped it the distance is actually 5.04miles!?!?! That is over a mile out! And considering I am training for a below 1 hour 10k at the end of the month (Nike Human Race, COME ON LONDON!) it is obvious that I have a way to go yet!

    Can anyone help? I have caliberated it since first syncing it and it appears to have actaully got worse. I have asked nike and they said “well if you not using our shoe what do you expect” and then gave some info about it being a pressure sensor and not a accelerometer?

    Someone please help me! Great website btw!

  23. Podophile says:

    Andy – The Nike+iPod shoe transmitter is not a pressure sensor, regardless of what Nike tells you. Experiment with your transmitter on a different shoe or in a different location on your laces. Make sure your pouch is fastened snugly to your shoe and that it’s not moving when you run.

    Good luck.

    I found that if you had a small mag light that came with a holder that it works great as a sensor holder. Using the belt loop for the top part of the shoe laces you then can tuck the rest behind the laces toward the tip of the shoe. the holder i had was a big longer then the tongue of the shoe so i folded the bottom part back over it self and it does look pretty cool.

  35. blpx99 says:

    I own a pair of La Sportiva trail shoes that happen to have a fabric cover over the the shoe’s tongue forming the perfect pouch for the Nike transmitter, no shoe hacking required. I noticed this surprising, undocumented feature of my shoes after buying the device on a whim and then wondering which shoe hack I’d need to make it work. Turns out the transmitter fits securely and safely into the shoe as-is. Who knew?!

  36. Anna says:

    Thanks for this! I looked around and your hack was the most secure for the least amount of time. The most difficult step was STITCHING. Oh my gosh, I had no idea it would be so hard to push it through the fabric; I broke two needles! I found wiggling took some of the stress off the needle and prevented it breaking. Third times the charm! ;)

  37. dragnfly says:

    I ran today with my new Nike+ sport kit sensor in my shoe for the first time…. I ran on my treadmill so I could test the accuracy of the thing. The two weren’t even close. Gonna try to calibrate the darn thing on tomorrows run. Any suggestions?

  38. Podophile says:

    @dragnfly – The Nike+iPod kit is not especially accurate on a treadmill. It works best when you’re actually running on the ground.

  39. Siobhan says:

    I got one of these a few days ago, but I refuse to buy the shoes because i love my asics. But try as I might, I cannot get my ipod to even link up with the sensor. I’ve tried what you suggested above, and it doesn’t seem to matter where I place it, I just cannot get it to work.
    I’d be so grateful if you could help, I was really looking forward to using it!

  40. Podophile says:

    @Siobhan If your sensor isn’t linking with your iPod, you probably have a defective sensor. It’s not entirely uncommon. You should be able to exchange it for a new one.

    Also, if you’re using an iPod nano, make sure you have the receiver plugged into the iPod. This can be confusing because the iPod touch and iPhone 3GS have the receiver built in. The nano doesn’t.

    Hope this helps.

  41. Brian Casteel says:

    Thanks for putting this up. It gave me just what I was looking for to secure my new sensor so I could better track my performance. Industrial velcro for the win.

  42. Brian Casteel says:

    As for pushing through the tongue fabric, I completely agree. I bent a needle pretty good, but ended up using my Leatherman to push/pull it through.
