K-Swiss, which is designed in California, is pushing its new Tube technology pretty hard. Here we see the K-Swiss Tubes Run 100 in a new colorway of Charcoal/Silver/Black-Fiery Red, which helps bring out the intricacies of the shoe.

The upper features a breathable mesh with synthetic overlays and trims. The mesh is dominated by charcoal, while the synthetics and overlays use the other colors as accents. K-Swiss designed this shoe for the neutral to under-pronator who requires lightweight cushioning, and with the added cushioning provided by regionally specific Tubesâ„¢ technology, these should make a solid purchase for the runners out there. They are available now for $79 at Zappos.
