Boa IP1 System:
fi'zi:k Boa shoes are secured with the revolutionary closure system Boa IP1. fi'zi:k have harnessed the highly accurate tightening , immediate release and minimal weight of the latest four -point attachment IP1 Boa closure system . It's lighter, cutting easier to use and less focused on closing pressure than a ratchet, and more accurate and secure than a Velcro strap wrap-over. The latest Boa IP1 closure system makes fi’zi:k’s B series shoes lighter, faster and more comfortable.
Custom unidirectional carbon or carbon reinforced nylon soles mean every precious watt goes straight into your pedals. Sculpted foot-beds and supportive heel forming keep feet securely cradled without any hot spots or crush zones.
