Fitness shoes (or toning footwear) are footwear that help to tone up your muscles and can help you lose weight. What a great marketing idea was my first thought when MBTs and Fitflops first started this footwear mega-trend. But the benefits of promoting better posture control and mimicking barefoot walking ready stack up. What's more wearers really do attest to how these shoes have eased back pain and sore joints. I've spoken to many people first hand and they love them - "most comfortable pair of shoes I've ever owned" one friend told me. The top brands of the genre are MBT, Chung Shi, FitFlop and Skechers Shape-ups.
