THE PROBLEM MOISTURE IS THE ENEMY For a runner, moisture is the foot s worst enemy. Moisture causes painful/race-ending blisters, Athlete s Foot, odor causing bacteria and over-all discomfort. Runners feet are going to get wet either from sweat, puddles, wet grass, rain, or by getting splashed at a race water station. In cold/freezing weather, moisture pulls heat away from the skin 23 times faster than air, reducing the temperature so rapidly that wet feet become painfully cold and much more susceptible to frostbite or Non-Freezing Cold Injury. Marketing Hype Can t Escape the Laws of Physics Wicking fiber socks all claim to keep feet dry. However this is marketing hype and doesn t change the facts that wicking fiber socks are not able to keep feet dry. Most wicking fibers are made from polyester, acrylic, nylon or wool and are Hydrophilic (water liking) because they have positive & negative charges on their surfaces. This attracts the negative & positive charges of the water or sweat molecules. Moisture sticks to wicking fibers Because wicking fibers attract moisture and are next to the skin, they hold moisture against the skin, keeping skin wet. Once wet, wicking fiber socks remain wet until well after the sweating stops and the slow process of evaporation inside a shoe takes place. Wicking fibers hold moisture against the skin WICKING FIBERS OUTSIDE WICKING FIBERS INSIDE SKIN WICKING FIBER SOCK (SWEAT) Wicking sweat across the skin Wicking fiber sock manufacturers say their socks wick moisture away from the skin. This is misleading as wicking fiber socks also wick sweat across and towards the skin, which helps keep the skin wet. Wicking fiber technology works better for a shirt were the sweat can evaporate to the open air, versus a sock that s trapped inside a shoe where little if any evaporation can take place. 4 photo: Luis Escobar

THE SOLUTION TECHNOLOGIES THE SCIENCE OF KEEPING SKIN DRY Dryness Only 2 Different Technology Layers Can Provide The laws of physics dictate that no single fiber technology can attract and repel moisture at the same time. To overcome this, drymax products utilize two opposite type fiber technologies interwoven to form inner and outer layers. drymax FIBERS REPEL MOISTURE Super Hydrophobic Fiber Technology drymax fibers do not wick because they are Super Hydrophobic (moisture repelling). At the molecular level, moisture doesn t adhere to the inner layer of drymax terry loops. drymax molecule Removing Sweat From The Skin Because moisture does not adhere to the drymax fibers, they are able to mechanically lift sweat off the skin like a squeegee and instantly transfer it into the moisture attracting outer layer without retaining moisture on the inside. DRYMA SOCK (SWEAT) OUTER LAYER DRYMA FIBERS SKIN DUAL LAYER OUTER S W E AT R E M O VA L INNER S Y S T E M A Self Contained System Guaranteed to Work We designed a self-contained Dual Layer Sweat Removal System so we did not have to rely on the shoes to help keep feet dry. This system works so well we guarantee it will keep feet dry and comfortable in all types of footwear, in cold, hot and even wet conditions WHAT YOU WEAR ON YOUR FEET AFFECTS COMFORT AND PERFORMANCE.

COLD WEATHER RUNNING Are you selling the same socks in January as you are in July? RETAIL PACKAGING In cold or freezing temperatures, moisture is the skin s worst enemy. Moisture pulls heat away from the skin 23 times faster than air, and can reduce skin temperature so rapidly that wet feet feel painfully cold. Wet skin makes the feet much more susceptible to frostbite and Non-Freezing ng Cold Injury. Staying dry is critical to remaining warm, comfortable and safe in cold weather and no sock has proven to keep feet drier than drymax technology socks. The wind chill factor often causes the front part of the leg to become the coldest; therefore a third layer of drymax fiber insulation was added along the Cold Weather sock s leading edge.

THE BLISTER PROBLEM Foot Blisters are the Most Common Running Injury Blisters on the feet are the most common injury and seem inevitable when running long distances. One study in the Journal of Sports Medicine 2004;38:498-501 reported that up to 39% of marathon runners experienced foot blisters while running marathons. Runners can t physically run enough training miles to condition their feet not to get blisters for long distance races of 100+ miles especially if the conditions of the course are bad. In the past, the most successful runners learned to run with the pain of having blisters, calling them a badge of courage. Until now, there has been limited success in actually preventing blisters. Runners have tried everything to prevent blisters including Vaseline, skin lubricants, powders and tape. These may help for a short period of time, but are not effective over long distances. Oily lubricants can be detrimental as they prevent socks from effectively removing moisture from the skin. Foot Blisters Can Cause Further Injury A study to determine the association of blisters with subsequent injuries was conducted by RS Bush, SK Brodine & RA Shaffer with 2,130 male US Marine Corps recruits participating in initial physical training at the Marine Corps Recruit Depot in San Diego, California. The study found that recruits with blisters were 50% more likely to experience an additional training-related injury. BLISTER CYCLE Foot blisters are most common on the toes, heel, and ball of the foot. Blisters caused by socks usually occur when socks do not fit, their seams irritate the skin, and/or the socks become wet. Wet socks soften and weaken the skin, making feet vulnerable to blisters. Heat, moisture and friction work together to cause blisters, each contributing to the severity of the others creating a Blister Cycle. HEAT Excess heat normally radiates away from bare feet, but wearing shoes traps heat, elevating the temperature of the skin. Heat generated by physical activity can further raise the temperature inside shoes 20 degrees or more. MOISTURE BLISTER CYCLE FRICTION HEAT MOISTURE With higher than normal skin temperature, the body produces sweat to cool the skin by evaporation. Wearing shoes prevents evaporative cooling from effectively taking place, leaving socks and feet wet. FRICTION Moisture significantly increases friction between socks and skin. Higher friction limits skin surface movement, but still allows inner tissue movement. This shearing effect physically separates the two layers, creating a void. This void fills with fluid forming a blister. SHEAR LINE (tissues separate forming a blister) INCREASED FRICTION (wet sock sticks to skin) INNER LAYER (tissue) Normal Movement BLISTER Reduced Movement SKIN SURFACE WET SOCK INSOLE BLISTER FORMATON 826

CONTROLS FRICTION SOCK FEATURES ELIMINATES MOISTURE ANTI-BLISTER SYSTEM REDUCES HEAT ANTI-BLISTER SYSTEM - Several features work together as an anti-blister system to actively prevent the formation of blisters. 1) Exceptional 3D fit and five sock sizes, 2) Seamless insides, 3) An instep-hugging arch band, and 4) Because drymax socks stay dry, the skin stays dry too; therefore blisters normally caused by sweat or sweat vapor are prevented. 3D ADVANCED FIT - drymax s six sock sizes fit because they were developed on special 3D foot models which accurately represent the human foot as opposed to the 2D flat form that are the hosiery industry standard. Each sock includes an S, M, L, L, or L color size mark for easy match-up after laundering. S S M L L L COOLER FEET - All drymax Running socks with the exception of Cold Weather and the Trail socks, possess top and/or bottom air vents. These vents release heat/sweat vapors to keep feet drier & cooler. They re designed to work with the built-in vent systems in the latest generation of breathable running shoes. PROTECTIVE PADDING - Most drymax Running socks are designed using different levels of protective padding: Low-, Low, Medium, Medium+ and High. We use dense padding as opposed to thick padding, because dense padding protects the feet without adversely affecting the fit of the shoes. LD HEAT ESCAPES ACTIVE ODOR CONTROL - The antimicrobial in the drymax fibers fights odor-causing bacteria, helping keep socks odor free. Not a topical treatment, the antimicrobial is molecularly infused into our drymax fibers. Being non-migratory and non-toxic, the antimicrobial provides long term active odor control. LONG LASTING COMFORT & DURABILITY - The special fibers used in our drymax Socks have a comfortable springiness and do not get stiff, shrink or lose shape over time. They are designed to last a long time using the highest quality fibers, and abrasion resistant nylon fiber reinforcements throughout the entire sock. STAY DRY & COMFORTABLE - GUARANTEED drymax socks will keep feet drier & more comfortable than any other sock. If your customers do not agree, they can return socks with the sales receipt to Drymax Technologies Inc. for a full refund.
