Castelli Transition 18 Socks
The Castelli Transition 18 Socks are available in a range of bold colours and have a thin construction similar to a summer sock. Despite being engineered to be light, they still keep your feet warm and comfortable thanks to the Merino wool silk blend of fabrics.
Features
- Merino wool silk
- Thinner construction like summer socks so they don't take up as much space in the shoe
