In this instructable we'll build a Nike+ sensor pouch that will attach simply and securely to your shoe - without the need to buy a brand new Nike+ shoe, or any other crazy contraptions that cost up to $10!
You will need:
1) fabric (nylon, hard canvas or other durable fabric)
2) durable thread (denim, nylon, etc)
3) Nike+ sensor
6) velcro (1 inch)
Step 1: Cut Out
It's best to use a tough fabric like neoprene, or a plastic backing-type fabric such as harder nylon or even very strong canvas. The point is to make sure that it's sturdy and will withstand some abuse. You might also want to consider the running conditions - weather and humidity - in your fabric choice.
The cutout is pretty simple. Just follow these instructions and you'll have the right size for the Nike+ sensor
Step 2: Sewing
I used Denim thread to sew this together, as it's a tougher thread that usual. I don't know much about thread, but it seemed very tough for my purposes. You need to sew how the diagram shows - fold over the smaller piece, and sew it to the longer one (I know it's one piece, but it's easier to identify them this way). Anyway, 1 goes on top of 2. Over the top stitch worked for me, but maybe you have better skills/suggestions?
Step 3: Velcro
My favorite step! I love velcro, and it's the perfect material for this hack. Sorry about the diagram. The fuzzy piece goes on the side w/ the pocket, the hooks go on the other side (back-side) of the pocket.
Step 4: Closing
It's done. Simply slip the sensor inside of the pocket, string the side w/ the fuzzy velcro under 2 rows of shoe laces, and then wrap the pocket on top of the shoe laces so the two velco pieces can close. VOILA! It's a little pocket for your sensor, which is quite sturdy on top of the shoe.
