The Wire is sleeker and has a more uniform aesthetic look, better ventilation and more comfortable than it's predecessor - the Ergo 3.
In addition to the already mentioned upgrades this new 2013 shoe uses Sidi's own Tecno 3 ratcheting cable system, and replaces the old lower Velcro strap, claiming for even more displacement of pressure across the foot equalling for better blood circulation.
Sidi retains the adjustable and fully replaceable heel retention system which reinforces the top of the heel to improve the fit by securely closing the back of the shoe around the top of your foot.
