The Nike SB Portmore II Solar is one of Nike's lowest profile skateboarding shoes. Solarsoft foam provides the basis for the shoe, and moulds to the foot for a natural and comfortable fit. Making impacts easy to absorb, the foam is dual-density; a soft foam is essential for cushioning whilst a denser foam ensures protection and durability. A tacky gum rubber outsole allows the Portmore II to flex with the wearer's foot, something essential for a natural fit. An all-suede upper of a minimalist structure helps withstand wear and tear and prevents potential stitching loss. Extended saddle construction around the ankle gives necessary protection whilst avoiding bulkiness and the classic round-toe lace-up design ensures style as well as comfort.
