Toning or unstable shoes had been all the craze in the 2000's. The promotors of these shoes used to make remarkable promises for the shoe. claims ranged from encouraging weight loss to getting rid of cellulite to firming the buttocks to fixing sore backs. The shoes were built with a rocker on the sole geared towards increasing muscle activity to get those believed benefits. Sadly, the science didn't support the claims and there was a lot of lawsuits from disgruntled consumers and several companies were forced to negotiate multi-million dollar pay outs with the Ftc.
Whilst all of that is in the past you will still find some of these shoes on the market and they still do have some support from those people who are informed about the footwear. Toning shoes can affect the way that you move and then for some individuals that may potentially result in an improvement in some things like sore backs. At the same time, it may make some individuals with low back pain feel worse. There is a lot of effort being directed at studying precisely what the footwear do and precisely who will benefit from them and who may be hurt by them. Different people are going to react differently the shoe.
Foot doctors seem to especially like these types of toning shoes due to the kind of patients that they see. The rocker sole design of the shoe makes them particularly helpful for those with a sore great toe joint, as with the footwear the joint doesn't need to move as much. However, while that may be useful for that joint it does put more pressure on the ankle joint so might create or make worse issues at the ankle joint. It was issues like this that led to the legal issues in the past and need to be taken into consideration by anyone promoting or using these shoes. They do have their uses and they may help for the right people with the appropriate condition.
