Patented Ventairé Sole - Better Than Barefoot™
A system so unique it's patented. The vents in the sole of a Piro Shoe are strategically placed to provide the maximum displacement of heat and moisture from your feet. But we also wanted to be certain your feet stay protected, so just under the insole of the shoe you will find a svelte layer of stainless steel mesh...think ultra light chainmail...to protect your precious sole. Light and strong...a winning combination embodied in the Piro Shoe. Weight-Shaving Technology
First, we built the shoe out of the lightest material available that would still hold up to the rigors of a daily pounding. Then, by venting the sole, we not only make them cooler, we continued to shave weight. The result? One of the lightest shoes your feet will ever have the pleasure to meet. They weigh in at a mere 6 ounces. What else weighs 6 oz? How about a tube of toothpaste or a small container of yogurt. Agion Antimicrobial: www.agion-tech.com
How it Works
Agion's customized antimicrobial solutions incorporate silver ions in a zeolite carrier. The silver ions exchange with other positive ions (often sodium) from the moisture in the environment, affecting a release of silver "on demand". The patented multi-faceted zeolite crystal carrier provides a three dimensional release mechanism (Figure 1) that provides efficient release of silver ions independent of particle orientation in the substrate.  Figure 2 shows the ion exchange process. Zeolite crystals containing silver ions are randomly oriented and distributed through the surface of a fiber, polymer or coating. In conditions that support bacterial growth, positive ions, in ambient moisture, exchange with silver ions at reversible bonding sites on the zeolite. The exchanged silver ions are now available to control microbial growth.
 Fighting microbes in three ways
Silver ions attack multiple targets in the microbe to prevent it from growing to a destructive population. This tri-modal action fights cell growth in three ways: • Prevents respiration by inhibiting transport functions in the cell wall • Inhibits cell division (reproduction) • Disrupts cell metabolism Machine Washable/Quick Dry All materials used in PIRO Shoes have been selected with durability and rapid drying in mind. From the EVA, non absorbent insole, and quick drying mesh uppers to the materials used for added comfort—the materials used to make Piro Shoes hold up to a spin cycle and promote wicked-fast drying times. Non-Marking, Non-Slip Outsole
As cool as it might be, the Piro shoe is way more than just a looker. Take a look below at the technologies built into the outsole alone. Beauty and brains. Nice. Water Channels
Channels have been placed on the outsole that are engineered to move ground water laterally away from the shoe. The channels significantly increase the volume of evacuated water and reduce moisture intrusion vertically into the shoe. Vents
Our unique venting pattern and vent size offers maximum air circulation while ensuring a structurally sound outsole. Other vented products use venting systems that compress under the weight of a step enough to significantly reduce air circulation. PIRO's US Patent-pending venting solution is produced using sound structural engineering principles and does not flatten out when worn. The design also maximizes vented surface area for superior circulation and comfort. Slip-Resistant
PIRO LLC references a SCOF (Static Coefficient of Friction) of .50 Dry and .40 Wet as the standard for slip-resistant footwear using the ASTM F1677 test condition. The PIRO outsole tests at .54 for dry and .44 for wet. For comparison purposes, the US Postal Service has set their standard for SCOF at .50 Dry. Other companies who specialize in slip-resistant products for Industrial use have set their standards in a similar fashion. Independent lab test results are available upon legitimate request. Custom density EVA
Designed to maximize wear time while creating significant cushioning, especially at the pressure points of the foot. The Piro outsole represents the perfect balance between ultra light performance and durability. |
