The Tubular series is inspired by 1990s running shoes with a futuristic design based on car tyres. The Tubular Shadow translates the innovative vision for today's streets. These warm-weather shoes come in an ultra-soft pigskin suede upper that's perforated on the inner side to allow air flow. They're built with a wrap-around burrito tongue to give a snug, comfortable fit. Visible moccasin-style stitches below the laces and at the heel create a handcrafted feel.
