On Running Cloudsurfer Running Shoe (Men) - Pearl/IvoryThe training shoe with computer optimized technology for next level cushioning. For an adapted and specialized version of our signature CloudTec technology, we left nothing up to chance. Using Finite Element Analysis (FEA), we simulated how each component of our prototype reacts while running. Using invaluable insights from this method, we created the optimal midsole for a seamless weight transfer from heel to toe. It's called CloudTec Phase and it
