SI-18 Rival Lace Up Sneakers Width:Medium A layer of cushioning polyurethaneThe 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.
