KEEN have called up their pals over at Gramicci to curate a collaborative take on the Jasper Zionic sneaker.

Designed for the trails but destined for the streets, together they've struck that perfect GORPcore for the urban jungle aesthetic.

They'll also have you know that they're not just concerned about having you look good, the shoe has to be good too.

Those suede uppers have been sourced from a LWG-certified tannery making them more ecologically conscious than regular leather. Other specs of note include their high traction rubber outsole, contoured fit and removable insole with arch support, they're also built with a stability shank for support.

Oh and speaking of insoles, they're actually infused with Eco Anti-Odor – which uses probiotics, not pesticides – to control odour from any potentially stanky feet.
