A shoe that has been tested and approved by athletes:
Before offering you these athletics spikes, we tested them with a panel of sprinters ranging from regional competitors to international athletes. "The 40 or so runners involved in the tests approved of the balance that the design team were able to find between feeling/support and a good foot width," reveals Driss, testing engineer at Kalenji. After three test phases, we are proud to present the final version of these AT Sprint shoes
