As we know that MBT Panda Sandals stands for Masai Barefoot Technology. The Mbt Panda Birch strengthens and tones muscles in the feet, legs, rear end and stomach. It features full grain leather uppers, microfiber lining along with a microfiber sockliner to improve air circulation and conduct moisture away from the foot and a dual board traction outsole. They are very fashion and cool. It is your 2010 summer best choice.
