The SI-18 Rival takes inspiration from some of our heritage models from the 1980s and 90s. By taking the upper from the Si-18 Rannell training shoe and putting it on a cup sole bottom inspired by the iconic Si-18 Premier tennis shoe, we have made a sneaker that is fresh and new yet still authentic to our heritage tennis roots. • Synthetic Leather Collar Lining • Molded Rubber Outsole • Die-cut EVA Insert Midsole • Die-cut EVA Sock Liner • Lace Closure
