So, how can they be this effective? What's the magic behind these shoes? Well, the secret is in the construction behind them. The engineer Karl Muller, who developed the shoes, created them to imitate the sensation of walking on a soft surface. This because he found that the Masai people (therefore the name), who walk barefoot on different surfaces, never suffer from back problems. He realized that the reason we in the west have so much back and neck problems, was because we mostly walk on hard concrete and pavements. The body needs variation to work well and build muscles to support the body. So he started do construct a shoe with four in built soles in different materials, to imitate this way of walking. He succeeded and the success was a fact. Mbt shoes are used all over the world today, not least among the Hollywood celebs, that swear it's the best thing since sliced bread. They use them for cellulite reduction and for toning and firming the body. If you have a job that makes you to stand and walk a lot, the Masai shoes can work wonders for you. You won't be as exhausted in the evening as usual, because the Masai shoes helps you keeping your posture upright and support back muscles.
