The story told by Adidas was 2023 Western States winner Tom Evans wanted the trail running equivalent of the Adidas Boston. So, Adidas took the famous Lightstrike Pro midsole and combined it with TPU Energy Rods. This created a highly responsive race day trail shoe that remains nimble on variable terrain. Unlike carbon plates the 4 TPU Energy Rods act as an extension of our metatarsal bones allowing for a large range of toe-off directions without sacrificing energy return and stablity.

 

 

Most users of the Men's Adidas Terrex Agravic Speed Ultra want uninhibited speed and nimbleness. Those runners are usually local high school cross country runners, Run Through Time Marthon competitors and those looking for the big buckle at the Leadville 100. This shoe is not an everyday trainer. If you're on trail and or dirt roads in search of 3+ hours of speed this is your race day trail running shoe.
