In Pescia, Tuscany, the Guidi tannery has been working leather since 1896 -- over a century of understanding how skin behaves under tension, how it softens with heat and wear, how it holds a dye when submerged whole. The E29C open-toe sandal is a direct expression of that accumulated knowledge: a cone of full-grain kangaroo leather mounted to a flat leather sole. No buckles. No straps. No ornament. Just the hide and gravity.

Kangaroo leather is among the lightest and strongest hides available to any maker. It drapes differently from the horse and buffalo that Guidi is known for -- thinner in the hand, with a dry, papery grain that warms quickly against skin. The grey here is achieved through Guidi's signature object-dyeing process, where the fully constructed sandal is submerged in pigment baths. The result is a tone that shifts subtly across the surface -- paler where the leather stretches over the arch, deeper in the folds near the heel opening. Each pair absorbs the dye according to its own grain, making the color unrepeatable.

The silhouette is deliberately primitive. The upper rises in a single unbroken plane, open at the toe and open at the back, held in place only by the natural contour of the foot. The flat sole keeps the stance grounded. Over time, the leather will map itself to the wearer -- the creases, the pressure points, the particular way you walk -- until the sandal is less an object you own and more a record of the distances you have covered.
