The T-4 Air Carbon Composite features a super-perforated triathlon-specific upper for maximum drainage and ventilation, with a plush, brushed interior for sock-free comfort, fast transitions, and supreme comfort on the bike leg. A large pull-tab on the heel and the two wide hook and loop fastener straps (placed mirror-inverted) help to change shoes on the fly.

• Twelve Carbon Composite Sole is made with two different materials blended together, nylon and carbon fibre. It is made out of injected Carbon Fibre in a matrix of Nylon. The Nylon used doesn’t absorb water and doesn’t lose rigidity in hot or humid weather or as it ages. The result is a significantly lighter and stiffer sole
