The Rush TRK GORE-TEX dials up the support and protection with a suede leather upper and a rubber toe rand, backed by GORE-TEX for guaranteed protection from the elements. The upper balances the light and agile feel of a trail running shoe with the support and protection you expect from a hiking boot. Underfoot support, protection and traction come courtesy of the exclusive PRESA outsole with Interactive Kinetic System (IKS) Technology. The Dynamic Stabilizer Torsion frame supports the arch and wraps the heel on both sides, providing terrific rearfoot stability and torsion control so you can confidently tackle whatever the trail has in store.
