The Sica™ VR70 is ideal for riders who want full power transfer without sacrificing the durability needed to stand up to rugged trails and conditions. The upper features Giro's proprietary Evofiber™ material for superb fit, and complements the adjustable SuperNatural Fit Kit that allows custom tuning of your arch support. An Easton® EC70™ carbon composite sole offers pro-level stiffness and is finished with a tough, molded rubber outsole that provides protection and grip when you're off the bike.
The Evofiber™ Teijin® microfiber upper is lightweight, breathable and comfortable and reinforced by on-welded impact and abrasion protection. The N-1 ratcheting buckle and two Velcro® straps can be adjusted to ensure optimum power transmission. The offset strap "D-Ring" at mid-foot ensures a better pressure distribution and eliminates pressure points.
The Easton® EC70 outsole made of carbon composite is very stiff and helps to optimize power transmission to the pedals. When you have to go off the bike, the Vibram® mont molded rubber lugs provide high traction that can be improved by steel toe spikes (not included).
Due to the SuperNatural Fit Kit with adjustable arch support the footbed can be individually adjusted to prevent fatigue, and the Aegis® anti-microbial fiber keeps the shoe odor-free.
The N-1 buckle is adjustable in 3mm increments to tension the strap, with a quick release by simply depressing the upper and lower levers simultaneously. The design allows grit to be cleared easily for reliable function on- and off-road, and it has a low stack height. It offers two mounting positions and a guard that helps to prevent unwanted release of the buckle, and is compatible with Giro's previous shoe designs should a rider need a replacement.
The Giro SuperNatural Fit System combines a cycling-specific footbed with an adjustable arch support kit. By simply choosing from any of the Low, Medium and High arch support included in the kit, riders and fitters can independently adjust arch support to enhance fit and pedaling efficiency while reducing or eliminating common discomforts like hotspots, numbness and cramping. The system is available in men's and women's sizes, and incorporates X-Static® fibers in the footbed to fight odors and other bacteria.
Giro worked closely with the engineering staff at Easton® to develop proprietary outsoles that provide the most direct, powerfull connection to the pedals without compromising comfort. Using advanced modeling and proprietary fixturing in the extensive test lab, every outsole is engineered to provide ideal stiffness in 3 zones: Toe Arch and Heel, while maintaining the lowest possible weight and stack-height (as low as 6.5mm). Additionally, the flatter edges of Giro's outsoles allow the shoe upper material to conform to larger or wider feet (what Giro calla the "spillover" effect) without uncomfortable pinching or binding.
Giro footwear is built on proprietary cycling-specific lasts to create a fit that hugs the foot closely without binding, crowding or discomfort. The Precision Fit™ lasts are hand-crafted specifically for cycling footwear in whole and half-sizes that are differentiated between men's and women's shoes, in order to provide the most supportive and precise fit possible in a production shoe.
Evofiber™ takes the best attributes of mesh and microfiber, and fuses them into a single fabric that repels water and improves breathability throughout the shoe. By eliminating the extra seams and adhesives required to insert mesh panels, the durability, comfort and weight of the shoes can all be dramatically improved. Evofiber™ also holds shape exceptionally well, and is fast drying and easy to clean.
The Women's Series™ is a complete collection of fits, styles and prices that are uniquely tailored to female riders. Each Women's Series shoe is available with a level of details that is unique within the line, and also features specific sizing and patterning in order to support the lower volume and narrower heel of a woman's foot. The one thing that isn't different, is the level of performance since Giro use the same top-quality materials and technologies found in Giro premium men's shoes. All together, the Women's Series offers a range of options that suit nearly any need, and within more compelling styles than competing brands.
The Aegis® Microbe Shield is an anti-microbial barrier that permanently bonded with the fabric. It uses the power of a tiny positive electrical charge to inhibit the presence of odor-causing microbes that can cause discoloring or fading, so your shoes stay fresh and odor-free.
Sonic welding is a process that uses sonic waves and pressure to fuse two elements together permanently. Utilizing this process to add a layer of armor to soft fabrics results in a more durable bond, the so called Direct Injected™ Armor, that is also cleaner and more accurate than traditional adhesives, and lighter too.
