Ideal for anyone wanting a lightweight, breathable cycling sock for everyday rides or a coordinated Espresso kit look.
The Castelli Espresso 18 Sock is a technical cycling sock designed to complement your Espresso kit. Its 85% nylon and 15% elastane construction balances durability with a comfortable, supportive fit, while the breathable fabric is suited to regular riding.
With an 18 cm cuff, the sock gives you a clean, modern finish above the ankle without adding unnecessary bulk. The 50 g weight keeps it light on the foot, and its recommended 10°C–38°C temperature range makes it a versatile choice for warm-weather rides and milder conditions.
Choose the Mocha colourway when you want a coordinated Espresso look, or simply a dependable sock for everyday road and training rides. Sizes are available in S/M, L/X and XXL, with sizing based on shoe size.
