Wrap the foot pod thing in plastic, then duct tape, then duct-tape it to the laces of your shoes.
Make sure it's the right way up, and the right way round though.
Simple cheap solution guv-nor, the i-strap.... http://www.istrap.co.uk/
i've never used one as I have a footpod. I know of lots of runners buying the strap though or the more expensive alternative -
My wife has a £5 velcro holder that clips on the laces that she bought at our local running store, which is probably a more elegant solution.
i-straps seem to be ideal...... you can even pick your colour!
and at £2......... its a steal!
