Airplay IV Outsole
The Airplay IV is Duca’s first fully recyclable and spikeless outsole, reinforcing our commitment to producing eco-friendly shoes. Functional nubs across the whole sole help generate progressive stability and optimal grip, along with a slightly elevated heel height to provide the perfect stance. All specifically engineered by Fioretti for an uncompromised fit, and lightweight cushioning that won’t weigh you down.
Airplay IX Outsole
Trendsetting and highly functional, the Airplay XI outsole is ideal on and off the course. 5mm cone-shaped nubs across the outsole generate progressive stability, especially as you swing, to ensure optimal grip.
Airplay XII Outsole
The Airplay XII is a recyclable, innovative outsole from Duca, with every detail carefully considered. The B-Light rubber outsole includes 2-way twist triangle nubs, both conical and cube-shaped, on the pivot point of the foot, to ensure a firm posture, with optimal grip, traction and stability.
Our Materials and Construction
Duca del Cosma only processes high-quality calfskin and cowhide leather from Italy. For the exterior of our shoes, we only use the more resistant grain side of the leather. We treat our leather with a hydrophobic treatment directly after tanning to make it water-repellent without altering its natural characteristics.
Waterproof Shoe Membranes
A membrane is like a wall separating liquids and gas. Liquids can't enter, but vapor may escape, making our shoes waterproof while also being breathable.
For the interior finishing of Duca del Cosma shoes, we use a microfiber material with a membrane and waterproof tape sealing. We focus on testing waterproofness and functionality to ensure your feet remain constantly dry, while still being able to “breathe”. The upper leather has been treated in regular intervals to ensure humidity runs off and does not soak in, so that it maintains its suppleness. We guarantee our shoes are waterproof under normal wearing circumstances and up to 1.75" on the shoe from the ground.
