The new Zephyr features a 28/23mm stack height and 5mm heel to toe drop. Using Topo's proprietary ZipFoamª in the midsole, a light- weight TPU blended foam with more resilience and less compression set than traditional EVA. A rigid elastomer stability plate runs inside the midsole, helping stabilise the forefoot and aid propulsion during plantar flexion. An antimicrobial Ortholite foam footbed offers added comfort, while helping reduce foot odour. A breathable mesh upper with lightly printed overlays secures the heel and midfoot while allowing plenty of room for toes to spread and splay.
