It's the same foam we use in our top racing models like Cloudboom Echo 3.. We deliberately removed the Speedboard® to encourage faster post-training recovery and to lessen the weight. The Helion™ HF hyper foam acts as a bounce board below your foot and propels you forward. For max energy return, max cushioning levels and hyper performance.
