Adidas' Tubular technology is nothing new. It's been around since the '90s and was first inspired by car tires. But it's safe to say that the Qasa Racer brought a mainstream, or at least popular, interest in this doughnut-like sole. The Qasa is pricey, though, and most people don't like paying extreme resale prices at retail. 2014 saw the adidas Tubular, a mid-cut runner designed by Nic Galway, gain popularity because of its $110 retail price and its place between high-end and athletic sneakers. The Tubular was also there to show that adidas wasn't joking with its direction this year, either, and carved out a nice lane for the brand's Originals line. It's a super wearable sneaker that nodded its cap to adidas' past but wasn't confined by it. ? Matt Welty
