Giro: DIALED-IN FIT AND PERFORMANCE ON THE TRAILThe Cylinder HV+ mountain bike shoe offers the comfort you’d expect from Giro with the convenience and precision of a Boa dial closure. With a single dial and a set-and-forget front strap, you can get into your shoes and onto the trails in no time. The Boa L6 dial offers 1mm adjustment increments when tightening, and a macro-release function to get out of the shoe. The upper construction provides great support and breathability, while our proprietary co-molded nylon and rubber lugged outsole provides remarkable  durability with reliable traction on almost any surface.UPPER• Boa L6 (1mm + with macro release) retention with lower-volume strap• Toe and heel microfiber reinforcements• Synthetic upper• High-volume fitOUTSOLE• Co-molded nylon and rubber high-traction lugged outsole• Mid-foot scuff guard• Accommodates steel toe spikesFOOTBED• Die-cut insolesWEIGHT• 325 grams (size 42)
