The Tubular series is inspired by 1990s running shoes with a futuristic design based on car tires. The Tubular Shadow translates the bold concept for today's streets. These men's warm-weather shoes come in a lightweight knit upper that flashes an asymmetric look and has a dynamic mÃ©lange pattern on the inner side. A wrap-around burrito tongue gives a snug fit. Translucent tape over the stitch lines adds a smooth technical feel.
