Whats your opinion?FYou helped develop the unstable Masai MBT shoes. Does this design actually work?1_Niggs Answer: That is a little bit overstated. But the literature shows that shoes are a minor player in injury development. If you take a group of people and want to injure them, send them out every day for a 20kilometre run. A lot of them will be injured in three weeks. The major factors are the distance run, the intensity and recovery time, not the shoes.2_Niggs Answer: The problem is that if you go to a store and want to find your best shoes, you dont know what to do.

The major benefits are training the small muscles crossing the ankle joint, and a reduction of knee and lower back pain. However, some claims for these unstable shoes are overstated, such as the general muscle strengthening that they are claimed to produce.5_Niggs Answer: There are claims that there are fewer injuries when you run barefoot, but there is not yet enough evidence, or enough research, to prove that. If you look at performance, most papers suggest an advantage of 3 to 4 per cent. With a
