Can wearing a pair of "cellulite-busting trainers" remove cellulite?
Cellulite is an esthetic condition that affects the subdermis (i.e. the deeper part of the skin), and comprises superficial fat accumulation, skin looseness, water retention, connective tissue deformity, chronic low grade inflammation and toxin accumulation.
Removing cellulite fat from the butt and thighs with anti-cellulite trainers and flip-flops
Exercise, such as walking (with or without hyped up and expensive trainers) burns calories and consequently reduces the fat stores in the body and also tones the muscles. The fat reduction effect of any exercise cannot be focused on a specific part of the body, i.e. spot fat reduction can not be achieved solely with exercise. So, when you walk, run or do a set of squats you do not necessarily burn fat from your thighs and bottom - in fact stomach fat is usually the first to go with exercise.
Therefore, those so-called cellulite-busting trainers cannot help you lose cellulite or other fat from your thighs and bum - because the fat reduction effect of exercise can not be pinpointed to any specific fat tissue of the body. This has been known to science for decades and is beyond doubt, so such claims are un-scientific and misleading.
Removing fat from anywhere in the body with "cellulite-busting" trainers and flip flops
A pair of trainers that are difficult to walk on, such as the much hyped anti-cellulite trainers, may indeed make you work harder when you walk, and therefore burn some more fat. The difference, however, is negligible. Furthermore, as we saw in the previous paragraph, there is no guarantee that the extra fat burned will be cellulite fat and that it will not come out of your stomach, breast, face or other fat deposit instead. So, indeed cellulite trainers help you lose a bit more fat, but would you care for a difference of something like 1%?
Toning the skin with cellulite trainers
As we mentioned on the first paragraph, cellulite is an aesthetic skin condition - it clearly is not a muscle condition. Cellulite is characterised by loose skin, but it has nothing to do with loose muscles. Toning the skin and toning the muscles are two completely different things. Toning the muscles with exercise does not tone the skin above those muscles. Exercise only tones the skin in a slow, general way - not in a fast, focused way.
It is true the some anti-cellulite trainers encourage you to use your your buttock muscles (gluteus maximus) a bit more than if you wear normal trainers, but this is not cellulite reduction, this is slight butt lifting, and the two things should not be confused.
Furthermore, it is much faster to tone up the "glut max" with some running, squats or lunges, especially on the powerplate, than with a pair of unstable trainers. Running with those trainers, in particular, is not the smartest idea, as those unstable-by-design trainers increase the risk of sprain and other injury.
Posture improvement maybe - cellulite reduction definitely not
It is clear that these so-called anti-cellulite trainers cannot increase fat burning to anything but a negligible percentage, cannot focus the fat reduction on cellulite and cannot tone the skin. Connective tissue deformity can not be affected by those trainers either. Moreover, any potential effect they may have on the cellulite tissues' lymphatic drainage/circulation improvement (and subsequent toxin removal) is a tiny percentage of the benefit of walking itself - with or without fancy trainers.
In summary, anti-cellulite trainers do not reduce cellulite to the slightest, so to call them "cellulite-busting" trainers is misleading, to put it mildly. Having said that, I have personally tried those trainers for posture improvement and they did help me stand more upright and use my core muscles (mainly) and my gluteus maximus (a bit). On the other hand they also gave me calf pain when I wore them more than a couple of hours, so eventually I got rid of them...
Marketing and hype
The notion that a pair of trainers can get rid of your cellulite is as naive as the claim that certain underwear and stockings can remove cellulite because they contain "crystals woven into the fabric that emit far infrared rays which melt the fat". Or as ludicrous as the claim that special jeans or tights that contain caffeine crystals in the fabric can help you get rid of cellulite. Or as naive as body brushing. If only things were so easy... Basically, all these claims defy common sense (not to mention biology and science), yet millions of educated, and otherwise smart, women believe in them - all due to clever marketing.
By equating cellulite reduction to butt lifting they confuse women into believing certain trainers that "engage" the gluteal muscles bit more than normal can also "remove" cellulite. This is because most women do not know the difference between toning the muscles and tightening the skin, which are two completely different things. In fact, when the first "cellulite-busting" trainers appeared on the market and were sold on their merit (i.e. posture improvement) they did not sell well at all - mainly because of the way they looked (=horrible). However, as soon as some really cunning marketing executive suggested they be sold as lean, mean cellulite-fighting machines, sales sky-rocketed and a whole new industry (based on a myth) was created!
The moral of the story
If you would like to improve your posture, by all means buy a pair of those trainers. If you can stand their ugliness that is, because lets face it they are not the most stylish or fashionable trainers to wear. To women you look like you desperately try to fight cellulite, and to men you simply look like a nerd. However, if cellulite reduction is the main reason of buying them, well, how can I put it? Don't hold your breath...
