The shoe receives a bit of an upgrade from its original. On its upper, the Mars Yard 2.0 replaces the original Vectran with a polyester warp-knit tricot mesh (a more breathable material that induces fewer internal hotspots — not sexy, but honest). The shoe’s Red donning straps are now adhered with a stronger X box stitch. On the outsole, the tread of the SFB, originally protruding for use in the desert-like Mars Yard, has been inverted for more appropriate wear in urban environments. Finally, the Mars Yard 2.0 comes with two insoles, mesh and cork (which is optimal for sockless wear).
