Designed to complement the Nike + iPod Sport Kit, Sportsuit Sensor+ is a finely crafted neoprene and rubber pouch that allows serious runners to attach the Nike + iPod/iPhone wireless sensor to the top of their favorite pair of running shoes.

Works with iPod nano 2G, 3G, and 4G

I hit my shoe on something during a run i guess and the sensor was gone by the time i got back. Crapy.

Little expensive for such a little accessory (with shipping). Works just like it says it does. Fits nicely on your shoe. Only issue I had was that I couldn't tighten my laces as much as my other foot because it got in the way. It works fine to keep the sensor in place. My sensor wasn't working correctly after a week or so, but it's probably just the sensor itself and not this case.

Only thing I might note is that you can get it at someplace like BestBuy without having to pay shipping. I just didn't realize until after I had already bought this. It works though.

I use the sensor case with a pair of Asics Kayanos and I absolutely love it! The sensor fits in the case snugly, and I have no concerns whatsoever about the sensor falling off, incurring damage or getting lost. Like another reviewer said, keep it as far down on the laces as possible and make sure its velcroed on tightly for most accurate results.

(As a side note to this, even calibrated, my sport kit has never been 100% accurate, and this is just the nature of the device. It measures impact, so if your stride changes a little, or the sensor's not on tight, your sport kit might be a little off. Mine is always very close, which is as much as I think you can ask for.)

The only negative about the sensor case is that, when left on the shoe, it does make it just a wee bit harder to tighten the bottom laces, which is important for both running comfort and accurate metrics. I can't take any stars off for that, however. It's only a little extra effort to work the laces with the case on, and it's easy enough to take off, if needed. Overall, the reward of using the sport kit with my Kayanos is more than worth it!

I can wear my Nike+ Sensor in all my different running shoes. Easily changes from one pair to the next, so I can keep track of all my training runs. Calibration is exactly the same as in the Nikes.

The Nike plus sensor fits snug into the sensor case. When using this case, I calibrated the sensor using the ipod touch and was surprised that the sensor was tracking very close without any calibration. This was a very cost effective solution to the problem of Nike requiring special shoes for their sensor. Good job Marware!
