At first I thought the shoes may be custom made by the countries for their teams but upon further research I fond that the shoes are made by Nike and are called Flyknit. The running shoe world has never seen anything like these before!
The new Flyknit shoe was the product of four years of research and development, which yielded new machines for a fabrication technique that never existed before. The shoes feature stability, support and a form fitting thanks to a seamless upper with integrally knitted supports created by laying-in Nike’s Flywire braid which is designed to fit like a sock. Nike's Global Creative Director Martin Lotti recently said "Combining ultra lightweight engineering of Nike Flyknit technology with the performance innovation of our track spikes creates a unique running proposition. Nike Flyknit is a breakthrough innovation for the design and development of running shoes and we’re excited to be able to deliver this innovation for elite track athletes."
Reading comments by bloggers online, it appears that many people aren't that impressed by the shoes and don't feel that they will offer enough support for runners and athletes. But, if tons of Olympic Athletes are using them in London right now AND winning gold medals with them...that's enough reason for me to believe that they work and are here to stay.
The shoes are available at Nike stores (or online at Nike.com) and most sporting goods and shoe stores for around $150 USD. The shoes are available in over 10 different colors.
