Built on the TrekSport platform, the Trek Pro offers a three layer water resistant upper, incorporating a breathable membrane and tapped seams. The lining is also made using a three layer fabric system. The first layer, which touches the foot, has undergone antibacterial treatment. The second layer is a breathable and water resistant membrane. The third acts as a reinforcement for the other layers. The stitching of the upper and the lining have been heat sealed to make the shoe water resistant. The 4 mm shock absorbing expanded EVA insole protects the foot from bruising. The lightly cleated Vibram® performance rubber outsole delivers improved traction and plating protection on a variety of surfaces. A hook and loop closure finishes off this performance driven design.
