I'm a big convert to Earth shoes - have two pairs of trainers, two pair of their shoes, and as for half an hour ago - a pair of these:

(Don't worry I didn't pay THAT much for them - I always get mine from the Clearance/Bargain Basement section of the site!)
The shoes and trainers are supposed to help you burn upto three times more calories than walking in normal shoes - I dunno if that's the case but I've been a lot more toned and have a lot less cellulite in the past 6 months since wearing them. They have 'negative heels' which means the heel of your foot actually sits lower than the toes which affects the posture of your whole body. Only trouble is I now can't bear to wear heels or anything that puts my heel higher - as when you get used to these they are more comfortable than anything else!
The Clearance part of the site is constantly changing, so you have to keep an eye on it for bargains your size. They do half sizes (great for me as I'm a five and a half and they are getting harder to find in the shops) but also go down to tiny sizes and up to larger than in most UK shops. They come really beautifully packaged and you get little cotton pump bags for them (which we use to store our re-enactment shoes in - handy!)
Once you have ordered from them they send you emails with special offer codes - I got a pair of £110 trainers for thirty squid a few months back. The trainers work me so hard that I only wear them when running once a week - but I wear my other pair all the time for walking about and I'm used to them.
I have also got some Masai Barefoot Trainer sandals which aren't as pretty as the Earth ones but very comfortable if freaky looking. Have to say I have totally stopped wearing all my other shoes!
Thought I'd post here because for those of you who go running - or have any interest in fitness - I'm finding these make a big difference definitely to my bum and leg muscles and even having better posture, you look 10lb lighter! The trainers are great as I say for training in but I wouldn't run a race in them they really do work your legs hard!
