Soft grain leather upper with visible hand-stitching along the moc-toe seam, a woven leather knot at the vamp, and a flexible ridged rubber sole. Condition the leather every few weeks with a leather balm to stop the wine-red dye from drying and cracking along the stitch lines, paying extra attention to the knot detail where the leather is worked into a tighter twist. Wipe the sole free of grit so it doesn't get tracked into the stitching, and avoid soaking — spot-clean marks with a barely damp cloth instead.
