Place the shoe on a clean and stable surface.

Prepare the eyelet, the hammer and the "punch" tool.

Note: Take time to understand the punch tool and match the appropriate halves of the new eyelet to the matching sides of the punch tool. One half is for the inside; the other is for the outside.

On the sample shown here, the yellow arrow shows the inside half; and the green arrow shows the outside half.

Insert the replacement eyelet to the lace hole using your fingers. Take care to insert the outside half from the outside, and the inside half from the inside.
