In the ’90s, you couldn’t ignore éS, an offshoot of Etnies. For one thing, its team included names like Eric Koston and Tom Penny. At the same time, though, like DC, it took skate shoes to new heights of technicality. Eric Koston’s first model broke new ground with the advent of an air pocket, something that, until then, had only been seen on shoes by Nike. A visible air bubble in the heel was enough to turn this shoe into an instant classic. To no one’s surprise, this set off a design trend that saw almost every brand offer shoes with the exact same feature.
