R4B Uomo: fi’zi:k’s range of road cycling shoes is developed in collaboration with leading professional cyclists. The best technologies, materials, R&D, testing and manufacture techniques are used to deliver you the best shoes for road riding and racing, and trickle down throughout the range.

Why use BOA?

Glove-like fit: it gives custom comfort with smooth, even closure and no pressure points.
Powerful closure: once locked into place, BOA reels and laces stay that way.
Micro-adjustability: BOA reels offer seemingly infinite degrees of fine tuning.
Quick on, quick off: BOA saves time when seconds count.
On-the-fly adjustment: get easy, one-handed adjustment with a quick turn of the BOA dial.
Durable: made from aircraft grade stainless steel, BOA laces are stronger per gram than tank armour.
Lightweight: BOA closures shed water, mud and ice, shaving precious weight.

Adjusting the two straps closest to the toe will alter the fit and distributed pressure around the foot, enhancing comfort and performance.

Adjusting the BOA dial will alter the fit of the heel cup around the foot, increasing power transfer and maximising performance.
