The Zig Shark runner manages takes Reebok's often-used ZigTech to new heights. For this particular model, the zig zag outsole has been crafted at 20-degree angles. The purpose of this angular shift is to encourage the zig zags to bend backwards as the foot strikes the ground, which creates a soft, shock-free landing. With a synthetic and mesh blend upper, these will also keep you cool and comfortable. To top it off, the PU sockliner is removable and can be swapped with orthotics. Finish Line still has a wide selection of sizes available, so make your move!
