The Sidi Soft Instep Closure System 3 is for your Sidi Tecno 3 shoes - set sold as a pair - to bring new life to your Sidi shoes.
Compatible on shoes pre-2011 such as Tecno 3, Ergo 1/Ergo 2, Genius 5/Genius 6, Spider and Dominator 5/Dominator 6.
If you are unsure, simply measure the width of your current strap on your existing soft instep closure strap - it should be 18.5mm (if not, ie 15.5mm, you'll need the Sidi Soft Instep Closure System 2).
Installation of the strap is simple and replaces older worn and torn compression straps. Sold in pairs, but does not include buckles.
