The previously introduced Taka Hayashi x Vans Vault TH Sierra Trek Hi LX receives further refinement in the release of its second installment. Having already left his mark on a handful of Vans Vault creations, Hayashi has taken the liberty to revamp the outsole by switching the original crepe-based one with a Vibram bottom. The majority of the upper is constructed with soft Horween leather with the exception of a off-colored strip of embossed leather found at the arch of the mid-top shoe. Other details include contrasting leather interior lining, round textured lacing and top metal eyelets. Available in both beige and sunrise brown, the Vans Vault TH Sierra Trek Hi LX II is set to release early September as part of Vans‘s 2012 fall/winter collection.
