Giro Shoe Information
Giro has always set out to create new and innovative products for cyclists. A few years ago, Giro launched a line of footwear that follows that ethos, which enabled them to create unique shoes that would stand out against the competition.
Evofiber™
A specialized upper material designed by Giro to allow for the best performance. Comprised of a perforated microfiber, it allows for improved breathability, while the one piece design eliminates unnecessary seams. It is used on Giro's high-end road bike shoes.
Teijin®
Teijin® has built its name on creating high-quality fibers and materials for various uses across different industries. Giro wanted a material that would be super durable for their uppers, but was still lightweight, and the Teijin's microfiber was just that material. You'll find Teijin® microfiber in the uppers for some of Giro's high-end road and mountain bike shoes.
PrimaLoft®
Another company that has been making high-performance fabrics for years, PrimaLoft insulation is used in the Alpineduro winter shoes. PrimaLoft insulation is guaranteed to provide you with protection from the bitter cold, and is composed of post-consumer recycled material.
Precision Fit Last
All Giro bike shoes are built on the same last that is designed to provide you with high-quality performance, without cramping your foot. Giro creates different lasts for individual whole and half sizes, for both men's and women's shoes, allowing for the most natural fit possible.
Women's Series
The same Precision Fit Last that every shoe is built on, but optimized for women, which makes it slightly narrower as a result. All of Giro's women's bike shoes are built on these lasts.
High-Volume (HV) Last
HV stands for "High-Volume" and is Giro's way of indicating that a shoe is built on a wider last. The HV shoes are wide versions of other Giro shoes to better accomodate people with wider feet. Several of Giro's road and mountain bike shoes are available in the HV variant.
SuperNatural Fit Kit System
Designed as a cycling specific insole system with customizable arch support, the SuperNatural Fit Kit System enables long-lasting comfort by avoiding hotspots and cramping that may result from inadequate arch support. They are built with X-Static® fibers to reduce odors. The SuperNatural Fit Kit System is included with Giro's mid to high-end road and mountain bike shoes, or can be purchased separately.
Aegis®
The Aegis® Microbe Shield is used as an anti-microbial treatment for insoles to help cut down on odors. All Giro shoes that do not include the the SuperNatural Fit Kit feature an Aegis® treatment, except for the Rumble VR and the Petra VR, as do a few of the shoes that have include the SuperNatural Fit Kit.
X-Static®
X-Static® fibers are comprised of pure silver to allow for a natural anti-microbial treatment that helps prevent odors. It is a standard feature on most SuperNatural Fit Kit footbeds.
Poron® XRD™
Providing extra shock-absorption, Poron® XRD™ material is soft and flexible, but once it is impacted, it becomes dense enough to absorb the shock of the impact, without wearing down. It also has antifungal properites that allows for reduced odors and wear. Some of Giro's mountain bike shoes feature Poron® XRD™ cushioning in the heel.
Easton® EC90 ACC/EC90 Outsole
Giro teamed up with Easton® to make carbon outsoles that would deliver superior performance by maximizing stiffness, while minimizing stack height. The EC90 ACC are full carbon outsoles, and the stiffest soles found on Giro's shoes, and the EC90 is a carbon fiber outsole that, while a little less stiff, still delivers high-quality performance. The EC90 ACC soles can be found on Giro's high-end road bike shoes, while the EC90 is found on both the high-end road and mountain bike shoes.
Easton® EC70 Outsole
Another product of Giro's collaboration with Easton®, the EC70 outsoles are Giro's line of carbon composite soles. While they may not be as stiff as the EC90 soles, they are still designed to maximize performance, while reducing overall stack height. The EC70 soles can be found on most mid-range Giro road and mountain bike shoes.
DuPont® Zytel™ Nylon Outsole
DuPont® has always worked tirelessly to develop new and innovative products throughout its 200 years of operation. That's why Giro sought out DuPont's Zytel™ nylon for some of its outsoles. Zytel™ is stiffer and more durable than other types of nylon, meaning that you will get excellent performance that will last longer than most other shoes. The DuPont® Zytel™ outsoles are featured some of Giro's mid-range mountain and road bike shoes.
Vibram®
Orginally designed for mountain climbing shoes, Vibram® rubber outsoles can currently be found on thousands of shoes from different manufacturers across various industries. Giro chose Vibram® for use on some of their mountain shoes, because they wanted a high-quality, durable compound that would ensure excellent grip to pedals. Vibram® outsoles can be found on some of Giro's mountain bike shoes.
MR-1 Buckle
Built to be a truely micro-adjustable ratchet, the MR-1 Buckle allows two-way adjustment in 2mm increments. In addition to providing you with a secure fit, Giro has implemented a low-profile design, thus reducing stack height, to prevent buckles from getting damaged. The buckles are replaceable and can be found on some of Giro's high-end road bike shoes.
N-2 Buckle (Formerly MR-2)
Similar to the MR-1 buckle, N-2 buckle was designed as micro-adjustable ratchet that allows two-way adjustment in 3mm increments. Also like the MR-1, the low-profile design helps to prevent it from taking unnecessary damage. The buckles are replaceable and are predominantly found on Giro's mid to high-end road and mountain bike shoes.
