Magnifly 4 delivers the ultimate zero drop comfort on the road. The secure and breathable upper features a new look and is now made of a recycled engineered mesh, equivalent to three 16 oz. plastic water bottles per pair. New lace stays keep the tongue secure over the foot. We upgraded the dual-density midsole with ZipFoamā¢ for increased response and compression resistance. The antimicrobial OrthoLiteĀ® footbed offers additional comfort directly underfoot. A sweeping toe rocker design aids in propulsion and a smooth transition, while the widened 25 mm platform offers a smoother and even more comfortable ride. Strategically placed rubber on the outsole provides slip and abrasion resistance just where you need it.
