The Castelli Climber’s Women’s Socks are lightweight cycling socks made for warm days and long climbs. Built with minimal material, they help keep your feet cool, dry and comfortable when every gram counts.

If your usual socks feel hot, bulky or slide down inside your cycling shoes, these are a simple upgrade. The thin construction sits neatly in your shoe, while the support band and compression cuff keep everything in place from the first pedal stroke to the top of the climb.

Lightweight Build for Climbing

Castelli designed the Climber’s sock to cut weight wherever possible. The minimal, thin knit keeps bulk down inside your shoes, making it a smart match for women cyclists who love hilly loops, mountain roads and summer climbing days.

Cool and Dry in Warm Weather

Less material means more airflow around your feet. The lightweight fabric helps move sweat away from your skin, so your feet stay cooler and drier through hot Australian summer cycling.

Midfoot Support Band

A built-in support band wraps the middle of your foot for a snug, secure feel. It helps stop the sock bunching or shifting inside your cycling shoe, so you can focus on your pedalling instead of your feet.

Compression Cuff That Stays Put

The compression cuff holds the sock in place around your ankle without digging in. No more stopping to pull your socks up halfway up a hill.
