Great for any speed and any distance, the LunaRacer 4 combines the cushioning of a traditional shoe with the lightweight feel of a racing flat. Seamless mesh upper for a comfortable, distraction-free fit. Flywire cables wrap the midfoot for supportive lockdown that can be customized through the laces. Lunarlon midsole cushions and absorbs shock for a soft, springy ride. Waffle pistons in the outsole compress on impact then spring back to their original shape, adding extra cushioning and responsive ground feel.
