Knit? Neat! The Mesa's upper features a knit material designed for optimal flexibility and air flow, granting you breathability and reduced foot funk. The materials dry quickly should you step in a stream, puddle, or get caught in the rain. The mesh keeps your feet fresh, the natural foot-shape keeps you feeling good, the 4mm drop platform keeps you balanced, and the full rubber outsole keeps you grounded! Lems Shoes - Men's Mesa
