I gave Vibram FiveFingers a go several months back and am a total
convert; knee pain from running is now a thing of the past for me!

I wanted to bag some 'Injiji' or Vibram 'Lizard' socks to fit the shoes, but
they are pretty damn expensive. The shoes are not cheap, and I refuse to be
screwed £10 for just one pair of socks.

So I modified some cheapo 'five for three quid' socks and made my own socks
compatible with the FiveFingers - 'Tramp Chique' too, it's a whole new fashion
trend.
