The Chamber II stays true to the legacy of its predecessor and the brand’s original highly-acclaimed enduro and downhill bike shoe. It was co-designed by pro rider Aaron Gwin. Since Gwin is a downhill rider, components of this shoe are naturally applied for the purpose of the said sport.
Although it is an enduro/DH-oriented shoe, it can still be used for other mountain cycling activities. However, the shoe’s relatively heavier weight and bulk perform best in descending mountain biking endeavors.
Customized internal shank construction. Another update for the Giro Chamber II is the internal shank design. It features a Tri-Mold structure that’s specially designed to provide different levels of stiffness and flex for each zone of the foot: forefoot, cleat area, and rearfoot.
The forefoot zone is the most flexible for ease and comfort while walking. The cleat area is the stiffest to provide efficient power transfer. Lastly, the rearfoot offers a medium flex for stability off the bike.
The pair’s EVA midsole contributes to the enhanced cushioning and excellent pedal feel at the same time.
Optimal grip. Equipped with full Vibram Megagrip rubber outsole, the Chamber II works amazingly in muddy and slippery trails.
This mountain shoe employs a 2-hole cleat system. It works well with the following pedal models: Shimano XT M8000, Time ATAC MX2, and Look S-Track Race. The cleat area is recessed into the sole so wearers can walk comfortably.
Updated 10mm cleat setback. Giro added an extra 10mm of space in the cleat base to provide the cyclists with more room to position their shoe-to-pedal connection. This added 10mm allows placing the cleat-to-pedal connection under the arch to reduce fatigue and prevent long-term injuries.
Hard-wearing cover. Crafted from durable water-resistant reinforced microfiber uppers, this shoe can endure any type of terrain or condition thrown at them.
Double closure. For the shoe’s retention system, a combination of lace-up and hook-and-loop straps is employed. The lace-up provides a time-tested lockdown efficiency, while the strap allows further cinching and keeps the laces out of the crankset and pedals.
Extra protection. Rubber toe and heel reinforcements enhance the footwear’s overall durability and impact-protection against rock strikes and debris.
The Giro Chamber II downhill cycling shoe utilizes molded DH EVA footbeds with arch support. This type of insole is specifically designed to keep the foot in place despite the descending nature of the intended sport of this model.
