"What Our Gearhead® Experts Are Saying:""I put the Adidas Terrex Agravic Speed Trail Running Shoe through a long, technical trail race with significant elevation and loose dirt descents, and the Continental rubber outsole gripped through every sketchy section without a moment of hesitation. The Lightstrike Pro midsole strikes a balance between protection and ground feel that works well over long miles, and the Energy Rods add a noticeable snap to the stride that makes the shoe feel genuinely fast rather than just light.
