The Castelli Belgian Bootie 5 is an update on what is a very old classic. Way back, way - way back, when television had one channel and every photo was printed on paper (in black and white) The annual spring classics - always then held in horrid weather. Would see the racers don old socks over their leather lace-ups (and under there toe-clips) it's what you did to survive. Nowadays with triple laminated windproof breathable fabrics and carbon clipless pedals, you may think there is no place for the Flandrian tradition of a sock over your [carbon soled - dial equipped - 100g] shoes.
But you will be wrong, very wrong. The Castelli Belgian Bootie 5 provides a close fitting thermal barrier that allows excellent breathability, they keep your feet a little warmer but not too warm, they protect your shoes from dust and splashes and scrapes and when teamed with knee warmers make you look like a pro tour rider, what more could you ask for?
Handy Cafe tip - wear your Castelli Belgian Bootie 5 under regular shoe covers for better breathability and warmth on those real brass monkey days.
