The human foot is a marvel of natural engineering. The bones, muscles, joints and ligaments in your foot coordinate to create a smooth progression from heel to forefoot with every step. That's why the entire focus for the GEL-Kinsei® 3 has been to make it more adaptive to this natural transition. It has undergone significant redesign and improvements for 2009, retaining all the desirable attributes of the GEL-Kinsei® 2 while improving fit, feel and overall performance.
