The latest addition to Scarpa's Rush family, the Rush Trk GTX dials up the support and protection a notch with a suede leather upper and a rubber toe rand, backed by GORE-TEX for guaranteed protection from the elements. The upper balances a trail running shoe's light and agile feel 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 IKS system features impact-absorbing internal domes in key ground contact areas that function as mechanical shock absorbers. At the same time, the SuperGum rubber compound provides a secure grip on every terrain. 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.
