Vintage SIDI cycling shoes from the 1970s-80s. Size 41.5, which feels like 25-25.5 cm. I bought these new and had a cobbler add heels for easier walking. They are easy to walk in! I've only used them for a short test ride and walking around the house, never for actual cycling. They are vintage, so there is some staining on the leather. Please only purchase if you understand vintage items. Perfect for Eroica and vintage road racers!
