The Vibram FiveFingers Spyridon MR Trail Running Shoes are the first model actually designed for performance trail running. This shoe offers the perfect combination of feeling the ground beneath, whilst providing protection from the rough and rocky terrain. They have been designed to perfection for running on rough trail terrain and “off road.” It has the toughest available sole with a uniquely designed tread, which is reinforced and 3.5mm thick with 3D Cocoon technology moulded into the sole. They come with a zero heel drop, which means that the heel of the foot is as at the same height in the shoe as the ball of the foot to mimic the positioning of the foot when walking barefoot. The Vibram FiveFingers Spyridon MR takes its name from the first athlete to win the marathon in the modern Olympics, Spyridon Louis. The aggressive tread has been designed so that it gives the best grip possible in all directions on any type of terrain.
