Size 6 The hydrophobic rip-stop nylon upper has an ion-mask™ treatment that sheds water droplets without compromising breathability. ion-mask ™ is not a physical barrier to water, rather, it is an invisible nano-coating that makes the fabric totally hydrophobic. Being only nanometers thin, ion-mask™ does not add any weight and does not wash out or wear off with use. The Spider Rubber + J-Step outsole provides superior traction on slippery surfaces. Our Spider Rubber + J-Step outsole will stick to a grease-covered ramp. Wet rocks won't be a problem. Ion-mask™ technology actually prevents the materials in this shoe from absorbing any water on a molecular level. Drainage channels in the forefoot allow water to escape. A collapsible heel lets you slip in and out easily. Ripstop and mesh upper. Pre owned condition with minor wear
