The NOOSA TRI™ 15 running shoe is comfortable and ideal for a smooth running experience. And it’s lightweight, so you don’t have to compromise on speed during your training or a triathlon.The shoe's FLYTEFOAM™ technology is light and provides enough comfort without weighing you down. Plus, its comfortable upper design makes it easier to put on and take off during different stages of a triathlon. An increased toe spring means a high upward curve at the front of the shoe, which helps propel you forward and increases your speed during runs.
