Not to see to sure if this was mentioned previously , as unable to check old posts at the minute...but there is a trainer type of shoe being sold in pharmacies and some shoe shops that state, it can correct posture, help for cellulite, weightloss, reduce back pain etc etc . It has a rocker type of sole i think? Are they of benefit? and has anybody used a pair?.
I've never tried them so I can't comment on how good they are but I think the shoes your looking for are called MBT's [broken link removed].
My Mum's friend tried them but they made her feel sea sick so she gave them back
