When we're laced into the Salomon Speedcross 6 GTX Trail Running Shoe, gray skies and water crossings don't drop our tempo. This iteration is lighter and feistier than its predecessor with a featherweight upper fighting off thorny brush and deep, sticky lugs locking into mud and loose dirt. Backed by a waterproof membrane, this pair removes all hesitation from our stride for confident and powerful transitions through every mile.
