A company called Walk Easy makes lightweight forearm crutches in 8 or 10
different colors, sized for adults or children.  I believe they also make
walkers in 2 or 3 colors.  They have a website at http://www.walkeasy.com
    I have 2 pairs and the only problem I've had is that the original
equipment crutch tips were terrible, very unsteady and prone to slipping,
but they are a standard size and can be readily and inexpensively replaced.
