Genuine Sidi spare parts – this replacement Sidi Reinforcement Plate is for use with all models of Sidi shoe with the MTB sole.

These units are the female inserts to which the cleat bolts connect through the outer sole of the shoe. If you fail to grease these threads, you may have to drill your cleats out. In that event, the inner last may be cut to access this plate and replaced with these, saving your shoes. It is easier to just grease your cleat threads, though!
