Sidi shoes are known across the world for their excellent fit and ability to perform for a decade or longer over tens of thousands of miles. But the insoles--not so much. These high-quality, original equipment Sidi insoles are perfect for freshening a trusty, reliable pair of Sidi road or mountain shoes. Ideal for replacing worn, lost or nasty insoles. They are also an amazing value for an original equipment Sidi item. For half sizes, it is suggested to go to the next larger size as these insoles can easily be trimmed. As quality insoles can be hard to find, these can be used in other brands of shoes.
