A great pair of cycling socks can make a big difference to your comfort whilst riding. Breathability is hugely important for keeping your toes aired and free of sweat (so you don’t get blisters or overheat). That’s why Castelli have a large Air Mesh face along the upper of their 2015 Rosso Corsa 9 socks.
Mid way up the mesh fabric is a band to help support your foot within the socks. Sports socks get sweaty, and over time can build up some pretty bad odour. Luckily the Meryl Skinlife fibres which Castelli have used are naturally anti-bacterial.
A high ankle cuff (9cm) provides support further up your feet - the ideal length for cycling.
